Rangers manager Paul Le Guen will consider selecting Phil Bardsley if the on-loan defender can behave himself.
Phil Bardsley was involved in a training-ground bust-up
The Manchester United right-back was omitted from the squad for the games at Livorno and St Mirren following a training ground incident.
But Le Guen told the club website: "The Bardsley situation is now in the past.
"Now it is up to him to show he can behave well and have good spirit in the team. He must learn his lesson. I will think about him in the future."
The 21-year-old was axed for the Uefa Cup win over Livorno after being sent off in training for a tackle on team-mate Thomas Buffel.
And Bardsley was not even on the bench against St Mirren on Sunday, even though Le Guen made other changes following the 3-2 victory in Italy.
At the weekend, the player's agent, Des Rowe, said: "Phil has spoken to the manager and told him he is committed to Rangers."
"I have talked with Phil and he is ready to rock and roll.
"He wants to play and show the Rangers fans, the club and the manager what he can do.
"He does not want the incident last week to be something which will hang over him.
"He was absolutely gutted to be left out for the Livorno game, but he just wants to show Paul Le Guen he was right to bring him to Rangers and he is desperate to be a big player for them."
