Rangers will be without David Templeton for their Ramsdens Cup tie against Queen of the South.
The winger could be sidelined for a number of weeks after suffering ankle ligament damage at the weekend.
Striker Andy Little also misses the quarter-final tie at Ibrox with a foot injury.
On Templeton's injury - sustained during Saturday's goalless draw at Annan - boss Ally McCoist said: ``David has obviously got a very sore one. The good news is that it's not broken.
``He has been for an X-ray but there is massive swelling and there looks to be a good bit of damage to the ligaments unfortunately.
``We are waiting on the swelling going down and then David will get a scan in the next few days.
``I couldn't put a timescale on the return from injury unfortunately but it's not great.''
Second Division leaders Queen of the South travel without recent signing Paul Burns.
Burns is cup-tied after playing for Dunfermline earlier in the competition.
The Doonhamers will also be missing Stephen McKenna through suspension, however player-manager Allan Johnston has no injury worries to contend with.
Johnston could pick himself to face one of his former teams, saying: ``While I have experience of games like this I will only pick myself if I can justify it. We have a lot of young players desperate to do well so I need to get the balance right.
``Rangers may be in the league below us but they still have top players. However our plan has to be to defend from the front.''
