Red Star Belgrade v Rangers (0-1)
Rangers striker Daniel Cousin travels with the squad to Belgrade despite struggling with a calf injury.
The Gabon international faces a late fitness test following the knock picked up in the victory over Kilmarnock.
Chris Burke and Alan Gow have been added to the squad and Smith has no other injury concerns ahead of the third qualifying round second-leg tie.
Red Star are at full strength after absentees from the first leg in Glasgow recovered from injury.
Rangers boss Walter Smith said Cousin had recovered well and his fitness would be assessed later.
"Daniel is still doubtful, but obviously he's a bit a better than he was after the game on Saturday and even yesterday," Smith said.
"So we're hopeful that if there's the same improvement then the possibilities of him being fit are greater now.
"We didn't think he was going to make it at all but now he has a chance."
