Redskins right tackle Jon Jansen

vs. left defensive end

Adewale Ogunleye

Jansen will be playing with a soft cast after breaking a bone in the base of his left thumb during practice this week. Jansen could use his full health against Ogunleye, a talented pass rusher. But after missing last season with a ruptured Achilles' tendon, Jansen should be energized merely by being on the field today. After being traded by the Miami Dolphins last year, Ogunleye finished with only 51/2 sacks and suffered a calf strain that required offseason surgery. But this preseason, Ogunleye resembled the elite pass rusher who recorded 15 sacks in 2003, spurring Chicago to acquire him from Miami. Jansen, a better run blocker than pass blocker, faces a steep challenge.

Bears wide receiver

Muhsin Muhammad

vs. cornerback Shawn Springs

Muhammad uses a blend of speed and size -- he's 6 feet 2 and 217 pounds -- to outmuscle most cornerbacks. Last season with the Carolina Panthers, Muhammad recorded an NFL-best 16 touchdown receptions and 1,405 receiving yards. But the 6-0, 204-pound Springs showed an ability to limit big receivers such as Terrell Owens of the Philadelphia Eagles during stellar performances last season. Springs has vowed to play even better and will get his first chance against a top wideout. Although Justin Gage starts, Chicago uses a committee approach for its number two receiver, including Bernard Berrian, Mark Bradley and Bobby Wade. Chicago will be hard-pressed to score points if Springs contains Muhammad.
