Yes, it was expected. Still, losing cornerback Nathan Vasher is just going to make the Chicago Bears' goal of winning the NFC North a little bit tougher.
Vasher has had his difficulties this year, but so has the defense as a whole. It's never easy to lose a starter, let alone one in charge of shutting down one of the opponents top receiving threats. Thankfully for the Bears, they're playing the Vikings, which means their best threat is Bernard Berrian. If Charles "Peanut" Tillman can handle that, then Corey Graham (who gets the start for the injured Vasher), will do just fine.
As a Bears fan, I'd be more concerned if Chicago placed a linebacker or d-lineman on IR, seeing that "The Real" Adrian Peterson lurks in the Minnesota backfield.
