MONTREAL - Anthony Calvillo is expected to sit out a second game with a bruised sternum, but Adrian McPherson is coming off the injured list in time to take over as the starting quarterback for the Montreal Alouettes.
McPherson did most of the preparatory work in practice on Tuesday while Calvillo took only a few snaps.
Calvillo said he felt good and should be ready to play, but coach Marc Trestman said it is unlikely he will dress in anything but a third-string role when the Alouettes play at Hamilton on Saturday.
''The chances of him playing are not very good from my standpoint,'' said Trestman. ''I'd be very cautious and err on the side of making sure he's fully recovered.
''Just because he feels great doesn't mean he's fully recovered. It would be very difficult to say he would be playing on Saturday. He could be there as the third and if he has to finish a game, do that, but never to put him in a position to take any kind of a hit this week. It would take a lot of convincing to pull me in another direction.''
Calvillo was injured just before half time in a win against Winnipeg three weeks ago. Chris Leak finished that victory and started the Alouettes next game against B.C. on Friday night, but left in the third quarter with a hip injury.
Trestman said Leak, who had an MRI exam on Tuesday, was still sore and would not dress in Hamilton.
Ricky Santos is likely to back up McPherson against the Tiger-Cats.
''I felt good,'' said Calvillo. ''I tried to throw on the run and make all the throws I need, torking my body around, and I really did not feel it whatsoever
''My (chest) and shoulder are still a little tight and sore, but I'm hoping that goes away in the next couple of days.''
McPherson tore the MCL in a knee during training camp and spent the first nine games of the season on the injured list. He will wear a brace for the rest of the season.
''Maybe three or four weeks ago I felt pretty good, but it was great to get the extra couple of weeks to rehab,'' he said. ''I'm excited about possibly getting the opportunity. I felt great.''
Trestman said defensive end John Bowman, who suffered a bruised thigh in the loss to B.C., should be able to return, but that backup defensive lineman Pat McDonald will be out longer with sore knee.
Linebacker Diamond Ferri is expected to return from a stomach ailment.
