That's it. Benfica cling on for a 2-1 win that means the final qualification spot will be decided in the last week of group matches. Celtic are still in the driving seat, though, as they entertain Spartak Moscow at home. Benfica, meanwhile, have to head to Barcelona.
Salvio off, Jardel (a centre back) on. Here comes the free kick...
Almeida fouls Samaras, then makes absolutely certain of receiving a booking by smashing the ball somewhere towards the moon. Chance here for Celtic to load the box as we move into stoppage time. If only Mulgrew was still on the field...
Wanyama penalised again, and the referee decides it warrants a yellow card this time around. Nothing naughty in the foul, perhaps given as much for an accumulation of misdemeanours. That booking means the midfielder will now miss what looks set to be a crucial final group game against Spartak Moscow.
Ledley heads off for Watt - he scored 11 minutes after coming on against Barcelona. He's got about the same amount of time to try and do the same tonight. Remember, a score draw here in Lisbon sees Celtic through to the knockout stages.
Matic - who has been solid in the middle of the park for Benfica - is replaced by Maxi Pereira. Celtic, meanwhile, seem to be readying super-sub Tony Watt down on the touchline.
Melgarejo becomes the first Benfica player to see a card after blocking off Lustig down the right.
Lima is heading off the field, with Nicolas Gaitan taking his place.
Garay succeeds where Lima failed just seconds before - a right-wing cross is nodded back across by his fellow centre-half Luisao and the former Real Madrid man smashes in a right-footed volley.
Here comes the second change for Celtic - Brown, who has missed seven games this season with a hip problem, makes way for Kris Commons. Samaras takes over as skipper.
Sky Bet update: Benfica are building up the pressure on Celtic, but the Bhoys excelled in the same situation against Barcelona - they're now 7/1 to nick this one tonight.
Ledley becomes the second Celtic player to be booked - it was a good, lunging tackle but you simply don't get away with them these days. In my Sunday morning league he'd have got a round of applause and a pint bought for him in the pub afterwards.
Joseph Griffin has tweeted in - he fances a 2-1 Celtic victory. That'd be typical wouldn't it, waiting so long for an away win in Europe's premier club competition, then getting two in the space of a few months!
Benfica 1 Celtic 1 - The Scottish champions have one foot in the knockout stages. Another 45 minutes of the same and they will join Barcelona in qualifying from the group.
Samaras is the first man into Mr Kassai's book when he's shown a yellow for declaring his frustration at being penalised down the left wing.
Samaras! It's 1-1 in Lisbon!
Aidean in Dublin: 'I believe even though we have allowed Benfica to score, we still can come back and win, Our performances away v Spartak Moscow and Barcelona have shown us we can do, but we need the Spirit of Lisbon 67 more now, I feel 2-1, Samaras and Hooper.'
Sky Bet update: Celtic are now 16/1 to come from behind and win in Lisbon.
GOAL! Celtic fall behind early on, it's John in the right place to slam home a loose ball in the box.
Pre-match odds from SkyBet: 'Following their unforgettable defeat of Barcelona in their last Uefa Champions League outing, we've had plenty of punters backing Celtic at 5/1 ahead of this battle for second place in Group G. The Portuguese hosts are 1/2 for the win, while the draw (100/30) has been the least popular outright bet. Tony Watt, whose goal proved to be the winner against Barca, is forced to settle for a place on the bench, and he's 10/1 to score last. Gary Hooper starts and is 8/1 to score first, but Benfica duo Oscar Cardozo and Rodrigo Lima are joint favourites (100/30) to break the deadlock.'
