Rangers midfielder Lee McCulloch is a doubt for Saturday's clash with former club Motherwell after an injury setback.
A hip problem caused the 32-year-old to miss his club's previous match against Hearts, while he then sat out training as Scotland prepared for their Euro 2012 qualifier against the Czech Republic, which he was suspended for.
He was able to start against Spain on Tuesday, but only lasted 45 minutes of the 3-2 defeat before being replaced by Charlie Adam.
He is now a doubt for the visit of Well in the SPL on Saturday, while he is also facing a fight to make the UEFA Champions League clash against Valencia at Ibrox next Wednesday.
McCulloch said: "I felt my groin and that previous injury tighten up. I'm in for treatment so hopefully I'll not be out for ages."
But the emergence of 19-year-old Kyle Hutton in midfield could give Rangers boss Walter Smith options should McCulloch fail to make Saturday's game.
Hutton has worked his way into the first team this season, making his SPL debut against Kilmarnock and starting in the 7-2 Co-operative Insurance Cup win over Dunfermline.
He revealed he has been spurred on this term by his failure to make his club's summer trip to Australia.
"Not going on the pre-season tour just made me look at things and work harder," Hutton told Rangers News.
"It made me determined to make sure I could be involved.
"I got a chance in the Clyde game and felt I did well and then there was the Newcastle game at Ibrox.
"I got on in that game and although it was only 10 minutes it was another step and that was really encouraging.
"Then in the first SPL game the gaffer gave me the nod to go on. It was a surprise, I admit, but I hope I took it in my stride and the experience itself was brilliant.
"It was great to get 90 minutes against Dunfermline. I really enjoyed the experience and my next aim now has to be to get an SPL start.
"Things have been going really well. I didn't think I would have been as involved as I have been to be honest.
"I love the pressure that comes with playing for the first team. Obviously playing at Ibrox is something special and it hasn't fazed me so hopefully I can get some more games this season."
