Celtic have been handed a lifeline in the Champions League after their opponents Legia Warsaw brought on an ineligible player in the last two minutes of the second leg of the third qualifying round.
Ronny Deila's side have now, then, been reinstated back into the competition, as they look to make it the group stages of the tournament.
First leg nightmare
Celtic had a nightmare of a night in the first leg in Warsaw. They lost the game 4-1 and looked to be all but out of the Champions League.
Callum McGregor seemed to have got them off to a great start when he curled an effort into the top corner of the goal.
However, the Scottish team didn't score again in the match. Miroslav Radovic went on to score twice for Warsaw before half time.
The Scottish team's night got even worse when they went down to ten men after Efe Ambrose was sent off.
Warsaw looked top have been through after securing a 2-0 on the night in Scotland and a massive 6-1 win ion aggregate.
However Warsaw made a fatal mistake two minutes before the end of the game.
With two minutes to go the Polish club bought on Bartosz Bereszynski, however Bereszynski was meant to be suspended and was there illegible and could not play in the match.
UEFA have ruled that the Polish team have been thrown out of the competition which means Celtic are through.
Celtic get a 3-0 win and are therefore through to the fourth qualifying round on away goals as they scored one away goal in Poland and the aggregate score over both legs is 4-4.
Celtic have been drawn against Maribor in their final play-off round, as they look to progress to the group stages of the Champions League.
