Chicago Bears' QB Jason Campbell ready for opportunity

With starting quarterback Jay Cutler out with a concussion, Chicago Bears' backup Jason Campbell is confident heading into Monday night's road match-up with the San Francisco 49ers, Melissa Issacson of ESPN Chicago reported.

Cutler suffered the concussion on an illegal hit in the second half of last week's game against the Houston Texans. Campbell took over, completing 11 of 19 passing attempts for 94 yards and a 70.9 passer rating in an eventual 13-6 loss.

In his eighth season, Campbell has spent most of his career as a starter, first with the Washington Redskins and then with the Oakland Raiders. A coaching regime change and broken collarbone, respectively, ended his tenure with both teams.

But after watching Caleb Hanie go 0-4 in relief of Cutler last season, the Bears were looking to add a more experienced quarterback as a backup, and scooped up Campbell on the first day of free agency with a one-year, $3.5 million offer. Now, Campbell is determined to prove to the league that he is still a starting-caliber quarterback.

"You've just got to play your game because everyone knows if you haven't played in a while, of course you're not going to be up here like a Peyton Manning," Campbell said. "You have to do what you do and do it to the best of your ability. Jay is good at what he does and I'm good for different reasons."

For his career, Campbell has a record of 31-39 as a starter and a 82.6 quarterback rating.
