MONTREAL -- Safety Kyries Hebert insists it was a bug bite and not a left ankle sprain that caused him to limp off the field at the Montreal Alouettes practice on Wednesday.

He was joking, of course, but the team hopes the injury is not serious and that he will be able to play in the East Division final against the Toronto Argonauts at Olympic Stadium on Sunday.

"I'm OK. I think an ant bit me," Hebert said. "I'm going to get some Neosporin and get the bump down. It'll itch but I'll be all right."

Coach Marc Trestman said Hebert suffered "a little sprain.

"He appears to be OK but we've got to see how much it swells up. We'll see (Thursday)."

Hebert had 48 defensive tackles and led the CFL in special teams tackles with 28 this season.

Running back Victor Anderson, out with a concussion in the final month of the season, was back practising but won't be ready to play on Sunday. Trestman said he should be ready to go if Montreal reaches the Grey Cup game.

There was hope that injured linebacker Rod Davis would be ready to return, but the coach ruled him out for the rest of the post-season.

Defensive end Aaron Lavarias is expected to come off the practice roster to see his first action for the Alouettes to shore up an injury-plagued defensive line. That may force import receiver Bo Bowling to sit out.
