Celtic goalkeeper Artur Boruc is making good progress from his preseason shoulder injury.
"We'll look at him over the next few days and see how it goes, but it's not as painful as it was so it's looking better," said Hoops coach Tommy Burns.
"He's a big personality, a big character and someone you'd ideally want in the team. Mark Brown has done well for us but I think in European games you're always looking for the experienced guys. If Brown's got to play it will be big experience and big stage for him and I'm sure he'll handle it OK."
