Alfredo Morelos tonight emerged as an injury doubt for Rangers ahead of the New Year derby against Celtic.
The Ibrox striker limped off clutching his leg in the win over Motherwell just days out from the visit of Ange Postecoglou's side.
Michael Beale is hopeful it is nothing serious and just a bit of "tightness" but couldn't guarantee Morelos would feature.
He told BBC Sportsound: "I think he (Morelos) just at this moment in time had a bit of tightness.
"He has been playing with a few aches and pains hence why he didn't play in the Ross County game because he hasn't played much this year so the two games previous took quite a lot out of him.
"Let's hope that it is nothing serious but with Antonio (Colak) and Kemar (Roofe) back in training now that gives us more options in that area and that's what we need."
Both Colak and Roofe were available for Beale against Motherwell but he rested the pair in the hope of boosting their fitness for possible run-outs against Celtic on Monday.
"They were available, I chose to maybe give them more time," said Beale. "If they played then it's tomorrow off and they need to pick up on their fitness, the pair of them.
"One of them has obviously missed pretty much the whole season, the other one has missed the last five or six weeks. It has been frustrating not having both of them available but when I do get them back I want them to be in a good place where they can play for not only 10 or 15 minutes, they can really contribute.
"They are huge players for us along with players like Tom Lawrence who will come back in the coming weeks and that can only make a stronger Rangers."
