The Bears may be shorthanded again Sunday when they visit the St. Louis Rams.

Receiver Alshon Jeffery (groin) and running back Kyle Long (knee) were both limited in practice Friday and are listed as questionable for the game.

Jeffery missed the entire preseason with a calf injury, returned to catch five passes for 78 yards in the season opener against the Packers, and then missed the next four games with a hamstring injury he sustained in practice.

Since returning to action, Jeffery has tied a Bears receiving record with three straight 100-yard games. But the four-year veteran injured his groin Wednesday in practice and isn't sure whether he'll be able to play Sunday against the Rams.

"We'll wait and see," Jeffery said. "It hasn't restricted my movements too much. [I'll] just keep getting treatment and just getting better, see how I feel."

Forte is trying to rebound from a knee injury he sustained two weeks ago against the Vikings that forced him to miss Monday night's win over the Chargers.

The Bears running back said Friday that he's "pretty hopeful" he will be able to play in St. Louis and that he feels "a lot better than last week." But Forte knows that there's always a risk of aggravating an injury if you return before it heals.

"That's always a factor," Forte said. "If you aren't fully healed up and you go out there, then you can take one step forward and get injured and take five steps backwards. That's obviously not good to come back for one game and then be out for five or six weeks. You don't want to do something like that."

Defensively, Bears outside linebacker Pernell McPhee did not practice Friday and was listed as questionable for Sunday's game. The five-year veteran leads the team with five sacks, seven tackles-for-loss and 15 quarterback pressures.

"He does generate pressure on the quarterback," said coach John Fox. "Obviously we're hopeful that he's able to play. If he doesn't, someone else has to pick up that slack."

Those replacements figure to be Lamarr Houston and Willie Young, a pair of veterans who have been more productive in recent weeks than they were earlier in the season.

"Both of them came off season-ending injuries," Fox said. "We monitored them earlier in the season, throughout the preseason, training camp, even really early season. Really defensively ... we're stressing to improve every week and we think those guys have and you see some of that success here of late."

McPhee could play Sunday despite not practicing all week due to his knee injury.

"He missed practice time the past couple weeks, truth be told," Fox said. "Sometimes you try and get them to the game and hopefully they deal with it well in the game."

Other Bears listed as questionable include left tackle Jermon Bushrod (shoulder), center Hroniss Grasu (neck), linebacker Shea McClellin (knee), cornerback Tracy Porter (hip) and safety Antrel Rolle (ankle).

Receiver Eddie Royal has been ruled out of the game with a knee injury.
