Michael Bush will start at running back for the Bears on Sunday vs. the Rams.

The good news for Bears star running back Matt Forte is that he reportedly did not suffer the dreaded high ankle sprain against the Packers last Thursday, an injury that usually sidelines a player for four-six weeks. The bad news is that the ankle sprain he suffered will still keep him out for at least this Sunday's game against the Rams at Soldier Field:

Forte's timetable is unknown, but the sprain is not believed to be very serious, and my guess is that the main concern for the Bears is making sure Forte is healthy for the week four MNF showdown against the Cowboys in Dallas.

For now, Michael Bush will start at running back, and that's not something I'm too worried about, as he's a starting-caliber running back in this league. The 6'1", 245-pound bulldozing back started 16 games for the Raiders over the previous three years, and had 256 carries for 977 yards in 2011. He can carry the load. He's also a better receiver than you'd think with his size- 37 receptions for 418 yards (11.3 AVG) in 2011.

Armando Allen and Kahlil Bell (brought back this week) are both expected to be active, and will each likely see some playing time. My guess is that Bell will serve as the #2 back, and Allen will be featured in some 3rd and long situations (but hopefully the Bears don't find themselves in those situations either).

The Rams may not have their star running back for Sunday's game either. Steven Jackson left the Rams' victory over the Redskins last Sunday with a groin injury, and he hasn't practiced all week. He's officially listed as "questionable", and is considered a game-time decision. If he can't go, rookie Daryl Richardson would be the starter, and he looked impressive against the Redskins, running for 83 yards on 15 carries.

As for other injuries to monitor, Bears defensive end/monster Julius Peppers is listed as "probable" with a foot injury, but he had full participation on Friday, and I'd be beyond stunned if he didn't play.

The Rams have ruled out defensive tackle Matt Conrath, safety Matt Daniels, and left tackle Roger Saffold. Defensive tackle Michael Brockers, the Rams' first round pick in the 2012 NFL Draft, is listed as "doubtful" with an ankle injury. Left tackle Wayne Hunter and fullback Brit Miller are "questionable", but St. Louis Dispatch Rams beat writer Jim Thomas says that both are expected to play.
