Wales came from behind to beat Scotland in their 2014 World Cup qualifier at a blizzard-bound Hampden Park as both sides ended the game with 10 men.
Defender Grant Hanley gave the home side the lead against the run of play with a header from a Charlie Mulgrew corner in first-half stoppage time and the Scots looked a bit more comfortable after the break.
However, in the 70th minute, after Scotland forward Robert Snodgrass was shown a second yellow card for a challenge on Chris Gunter inside the home penalty area, Aaron Ramsey levelled from the spot before Hal Robson-Kanu headed in the winner just over a minute later, with Ramsey ending the game on a sour note when he was shown a straight red card for a 'last man' tackle on James McArthur.
Gareth Bale had shrugged off a virus and an ankle knock to take his place in the Wales side.
Gordon Strachan, in his first competitive match in charge of Scotland, sprang something of a surprise by including 21-year-old Blackburn centre half Grant Hanley alongside skipper Gary Caldwell.
The visitors started with purpose and in the first minute a slack pass by Caldwell out of his own penalty area was picked up by Ramsey and Hanley had to dive in to block the Arsenal player's drive.
Strachan's plans were disrupted a minute later when Fletcher injured himself on the way down from an aerial challenge with Welsh defender Ben Davies.
The Sunderland striker looked in some distress and he was carried off the park on a stretcher to be replaced by veteran striker Kenny Miller.
Wales kept hold of the ball and with some confidence which frustrated the home support and the Scotland players, with Snodgrass booked in the 10th minute for a lunge at Gunter.
Three minutes later a moment of indecision at the edge of the Scotland box between keeper McGregor and Hanley was almost costly, the Blackburn defender having to clear at the second attempt under pressure from Bale, who was being booed each time he touched the ball.
Another unforced error by Hanley saw the young stopper give the ball straight to Bale 35 yards from goal - but again the Welsh failed to capitalise.
Scotland's first meaningful foray up the park came midway through the first half and almost resulted in a goal, Burke's deep cross from the right headed over the bar at the back post by Miller.
If nothing else it offered the home side some hope but they appeared determined to shoot themselves in the foot and moments later McArthur lost possession inside his own half to help Wales on to the attack but again the move fizzled out
Scotland were being outplayed and another dangerous move ended when Bale's drive from 30 yards was parried away by McGregor before McArthur completed the clearance.
As the snow continued to fall, a decent move by the Scots in the 32nd minute ended up with Miller heading Snodgrass's cross from the left over and for the first time in the game Scotland looked as if they were getting up to speed.
Four minutes from the break a robust tackle on Bale by Hanley left the Spurs forward requiring treatment and he was given more stick by the home fans as he re-entered the fray.
The match looked to be heading for the break all-square but in the three minutes of added time for Fletcher's injury, Scotland took the lead against the run of play.
Mulgrew's corner from the right was met at the back post by Hanley and he headed powerfully past Boaz Myhill from six yards, delivering a hammer blow for the Welsh.
Scotland were given a further boost when Bale failed to reappear after the interval, denting Welsh confidence - and restricting the Tartan Army's vocal repertoire.
But after a period of Scotland in the ascendancy, without causing any real threat, there was evidence that the game was still in the balance.
In the 70th minute, after Hanley was booked for a foul on Williams 20 yards from goal, McGregor threw himself to his right to save Bellamy's free-kick which cleared the wall.
A minute later Snodgrass recklessly conceded a penalty - and earned himself a second yellow - for a challenge on Gunter in the box and Ramsey hammered the spot-kick in off the bar.
The Tartan Army were stunned but they had more to worry about barely a minute later when the unmarked Hal Robson-Kanu headed King's cross past McGregor from six yards out.
With five minutes remaining, and the game slipping away from Strachan's men, McGregor made a save with his feet from King's angled drive.
There was time for Ramsey to pick up a straight red card for a 'last man' foul on McArthur but the home side failed to capitalise on the free-kick.
However, there could be no real Scottish complaints about the result which will boost the Welsh for the rest of the campaign, even if their hopes of qualification remain slight.
