No move is official yet, but running back Kahlil Bell said he expects to be signed from the practice squad to the 53-man roster before Sunday's game with the Philadelphia Eagles.

Bell has been on the practice squad for more than two months, and he's up to speed on the offensive playbook and as importantly the role on special teams he would play, if he is active for the game.

"If the opportunity comes for me, I'm comfortable,'' he said. "I feel like I have a pretty good grasp on everything. Special teams-wise, we have a high standard here, and I think I'm pretty good in that area. Whatever they ask me to do, if I get that opportunity, I am just going to try to help the team.''

The Bears made it official and have placed running back Garrett Wolfe on season-ending injured reserve.

Wolfe suffered a lacerated kidney Nov. 8 vs. Arizona. Wolfe is expected to make a full recovery and he is signed through 2010.

Running back Garrett Wolfe is expected to miss the remainder of the season with a lacerated kidney.

Wolfe was hospitalized for three nights following the Arizona game on Nov. 8, and while the hope was that he would be able to return before the end of the season, that's not a possibility. Wolfe is expected to make a complete return, though, and general manager Jerry Angelo expressed a desire to see him receive more opportunities last week.

"He's a great kid and it's unfortunate,'' Angelo said. ``I was hoping he would start integrating more into the offense and [offensive coordinator] Ron [Turner] was using him more in practices, and he's done a good job on special teams. I wanted to see him take another step as a runner.''

The Holy Cross and Northern Illinois product had 22 carries for 120 yards this season, ranking him second behind Matt Forte. He caught two passes for 12 yards, but his most prominent role was on special teams. He's tied for third with nine tackles, eight of which are solos.
