Celtic manager Neil Lennon admits he has several 'nagging' injury doubts for the UEFA Champions League play-off with Helsingborgs.
The SPL champions take a 2-0 lead into Wednesday's second leg at Parkhead after goals from Kris Commons and Georgios Samaras in Sweden put the Bhoys in a strong position to reach the group phase.
However, both Commons (ankle) and Samaras (thigh) are doubts for the return meeting after missing Saturday's 4-2 win at Inverness Caledonian Thistle.
Defender Thomas Rogne (ankle) and skipper Scott Brown (groin) are also injury concerns and manager Neil Lennon will make a late decision on the quartet.
Lennon said: "We still have a few nagging doubts regarding the boys we left out at the weekend so we will see how they are tomorrow.
"Thomas has an ankle problem, Kris has an ongoing ankle problem and Scott (is a doubt) with a sore groin.
"Some might not be fit to play, some might, so we will just have to gauge that tomorrow.
"But apart from that, we came through the game at the weekend injury-free so we will have a decent-sized squad to pick from."
