Here's a look at a key matchup heading into Sunday's Week Five battle between the Bears and Panthers.
Bears' offensive line vs. Panthers' pass rush
The Bears are already down one quarterback because of protection breakdowns, and they can ill afford to lose another one.
Carolina may not have Julius Peppers rushing off the edge anymore, but it still has pass rushers who will make the Bears pay if they block as poorly as they did vs. the Giants — namely, starting DEs Charles Johnson and Tyler Brayton and backups Everette Brown and Greg Hardy.
OLT Chris Williams (hamstring) has been ruled out for a third consecutive game, so Frank Omiyale will once again get the call at left tackle while Kevin Shaffer is expected to get another start at right tackle. ORG Lance Louis is dealing with a knee injury, but the Bears' most recent injury report indicated he was a full participant in practice.
The Bears will probably not have to pass-protect as often for Collins as they had grown accustomed to doing for Jay Cutler, and Carolina's front four isn't as talented as the Giants' is. The Panthers don't blitz much, but keep in mind that almost all of the Giants' nine first-half sacks on Cutler in Week Four came when the Giants rushed only four.
There is pressure on Chicago's front five to prove they are not as bad as some have been saying one week after Cutler and Collins had to leave a game because of injuries they sustained while taking hits from pass rushers.
