Thanks for joining my live commentary tonight, I've been Mosope Ominiyi. Hope you enjoyed what was an eventful game and stay tuned for the full match report but until next time, have a goodnight!

Ireland can take heart from their display, but weren't clinical enough with their chances and paid the price. They've now got a must-win assignment midweek against Armenia, to avoid Nations League relegation.

Hendry booked after the full-time whistle as tempers continue to flare between the sides, not sure what happened but off-the-ball incidents have been all the rage tonight.

FT: Scotland 2-1 Republic of Ireland. That's it! Hendry and Christie seal a comeback victory for the Tartan Army, a point in Krakow will do as far as promotion to League A is concerned - but a disappointing defeat to take for the Irish, a cheap penalty and preventable cross early after the restart.

Scotland players having no issues winding down the clock in the corner...

Brady latest to be booked on the far side and he can have no complaints, sliding in late to thwart another Scotland attack.

Four minutes of stoppage-time to be played now, and Fraser could've put the icing on the cake for Scotland's comeback! Instead he rushes a strike on the counter-attack, curling well wide of Bazunu's far post.

Pair of yellow cards shown to McTominay and Knight as tempers continue to flare in the dying embers, a lot of pushing and shoving... Scotland won't mind this with the clock running down.

Three changes in quick succession: Robbie Brady on for McClean in the last few minutes now, while McLean and Adams replace goalscorer Christie and Dykes for the hosts.

Browne was adjudged to have handled McTominay's header, replays showed the same and Scotland complete the comeback. Can they hold on now?

GOAL! Christie sends Bazunu the wrong way, composed and slots it home - 2-1 to Scotland!

PENALTY FOR SCOTLAND! Questions raised and a lengthy VAR check after handball, Coleman booked for his protests too...

Egan with a timely block to deny McGregor, whose effort looked destined for the bottom corner.

Triple change in tow for Ireland: Browne, Coleman and Robinson on for Molumby, Doherty and Parrott. The visitors aren't resting on their laurels, they know this game is still there for the taking.

Egan is booked for a cynical, but necessary chopping challenge to stop a Scotland attack from progressing any further...

Doherty appears to be struggling with cramp, briefly receives medical attention and it's a timely stoppage in what has been a frenetic second-half thus far. Scotland still searching for the winner.

Bazunu forced to work for the first time in a while, he parries Fraser's powerful effort out for a corner... Doherty with a last-ditch headed clearance, thwarting McTominay at the far post from the subsequent set-piece.

Doherty gets touch tight to McGinn and Scotland players cry for a penalty after Fraser's ball into the area causes temporary havoc - nothing given though.

Ogbene already a nuisance for Scotland's backline, winning a free-kick in a dangerous area as McKenna is booked for hauling him to ground - Gordon almost conceding a horrific mistake through his pressing moments earlier.

Chiedozie Ogbene on now, in place of Obafemi - reportedly short of full match fitness with midweek in mind.

Double change for the hosts now, as Hickey - who just received medical treatment - trudges off, as does Armstrong. Ralston and Fraser on in their place just before the hour mark.

CHANCE! McGregor with another loose pass, this time Obafemi sprints clear and hurdles a Christie challenge before releasing Parrott... denied by Gordon! He should've made it 2-1 there!

O'Shea makes a last-gasp challenge to deny Dykes as McGregor chips the ball into his path, before Collins heads the ball out for a corner with McGinn probing at the far post.

McGinn drags a shot wide from distance and truthfully, there were better options than to let fly from there. Ireland need to weather the storm though now, they're under the kosh and second to each ball right now.

Wide! Doherty with a rough miscue after doing the hard work to create space for a shooting chance, after McGregor relinquishes possession cheaply.

Christie curls a cross into the area and an unmarked Hendry makes no mistake, leaving Bazunu no chance.

GOAL, SCOTLAND EQUALISE! Hendry levels the scoring with a header in off the post!

Second-half underway and Ireland already zipping the ball around purposefully in the Scotland half - no changes at the interval for either side.

HT: Scotland 0-1 Republic of Ireland. Cullen would've had a heart-in-mouth moment as the Scotland players bay for a second yellow in quick succession, but John Egan's well-struck effort gives the visitors a hard-earned lead at the break. Steve Clarke\'s men started intently yet lack the incision needed to get back on level terms.

Cullen is first into the referee's book for what appears to be dissent, after Knight fouls McGinn. Two minutes' stoppage time to be added on now.

Taylor and McKenna both active in opposite areas - the former looking threatening in the Ireland half, before McKenna produces an excellently-timed sliding interception.

Confirmation of that change, as Taylor replaces Tierney moments before Bazunu comfortably claims a Scotland corner too close to the Southampton goalkeeper after Dykes threatened a half-chance in the build-up.

Tierney trudges off down the tunnel, unhappy that he's unable to continue but especially after the earlier knock too, it makes sense they're being cautious and taken the decision out of his hands.

If the referee sees that in real-time, he probably gives a penalty. Parrott didn't attempt to play the ball, he panicked, and Tierney looks rather worse for wear as Greg Taylor receives instructions from the bench.

O'Shea with an important block, conceding a Scotland corner. From it, Tierney goes down clutching his head after an off-the-ball incident - replays show Parrott fouled him as he saw the Arsenal man advancing past him.

Parrott is penalised for a push on Tierney as they challenge for the ball and he latches onto a crossfield delivery, heading goalwards. Looks bemused at the decision but can't have any real complaints.

Armstrong shows good feet to weave past his marker with a body feint and loops another cross into the box, Dykes heads down for McGinn... who again snatches at the ball and Bazunu watches it wide of the post.

Wide! Armstrong fizzes a cross into the area, McGinn is unmarked but ultimately doesn't strike it cleanly on his weaker foot and it trickles out for a goal-kick.

Close! After good work in the build-up by McTominay, Christie looks to slip the ball through into Stuart Armstrong as he edges into the box, but the execution is slightly overhit and Ireland can relax again.

Very early days still but the crowd hasn't responded well to that early opener, feels like a gut punch and the Scots must string together some promising play to get their home supporters brewing again.

Will that goal whip Scotland into shape and produce the necessary response? Or can Ireland consistently defend well in numbers, potentially going to grab a few more in transition?

Egan producing a striker's finish in the area, after the corner was partially headed clear by Dykes - Molumby reacted quickest to flick it back into the danger zone before the Sheffield United defender smashed beyond Gordon at his near post! 1-0 to the visitors, at a very interesting time to score too.

GOAL FOR IRELAND! EGAN SLAMS HOME FROM THE CORNER!

Hendry makes a big block after McTominay gets stripped cheaply in a dangerous position, Obafemi lays off Parrott but the striker hesitates a touch too long and allows him to stifle the effort out for a corner.

That promising opportunity quickly fizzles out though, as Doherty shoulder-checks Kieran Tierney in an aerial challenge and is penalised.

McGinn gets a talking to by the referee, after a late sliding challenge on Jason Knight as Ireland have a chance to get players forward now.

Parrott's overlapping run breaches the Scotland backline, he wriggles his way free in the box and scores... but it's swiftly ruled out for offside! Linesman purposely let the play continue but replays show he was clearly off there.

Quick one-touch passing between four players sees Scotland gallop forward again, this time Scott McTominay finds himself furthest forward but his deflected effort is completely caught by Bazunu's gloves.

Christie fires wide from distance after another attack is partially cleared by a composed Nathan Collins, before Scotland again win the ball high up the pitch.

Bazunu rushes off his line to stop a potentially dangerous attack in his box, as Scotland advance intently with McGinn and Dykes among those charging in transition.

Kick-off! Scotland already look assured and purposeful in possession, it'll be interesting to see which players settle better here tonight.

The players walk out of the tunnel to a rapturous reception from a booming Hampden Park, ahead of a clash with big stakes involved for both. National anthems to come, before pre-match pleasantries.

Elsewhere in the same group earlier today, Ukraine were 5-0 winners against Armenia with goals from four scorers including a second-half Artem Dovbyk brace and now leapfrog Scotland into top spot. That result means, should Ireland win tonight, they'll be safe from relegation to League C.

Less than an hour to go until KO now, so check the article tab for my match preview before it disappears at kick-off! Scotland will be fancied to prevail, but Ireland have enough quality to cause another upset here. Whether they'll manage it, is another question entirely.

Team news has already filtered through, so check the line-ups tab for that. Aston Villa midfielder and Scotland captain John McGinn will make his 50th cap tonight, while the Obafemi-Parrott attacking duo starts again for Ireland in their first match of this international break.

As for Steve Clarke's side, they'll be buoyed by a morale-boosting 3-0 win over Ukraine midweek and fancy their chances of exacting more revenge against another side who got the better of them this past summer.

I'm Mosope Ominiyi and I'll be taking you through the evening's events from Hampden Park, as Group B1 in this season's competition intensifies. Anything less than victory for tonight's visitors will end their faint hopes of qualification to League A.

Good evening everyone and welcome to tonight's live minute-by-minute commentary, as Scotland and the Republic of Ireland prepare to collide in UEFA Nations League action.
