CBSSports.com's Eye on Football blog has all your Week 6 injury updates here...

* Ravens cornerback Lardarius Webb, arguably the best defender on this team, left the Cowboys' game late in the first quarter with a left knee injury after colliding with Dallas wide receiver Dez Bryant. Webb had to be helped off the field and had trouble putting weight on the leg. UPDATE: According to CBS Sports' Jason La Canfora, the team fears Webb suffered an ACL injury. There's also this:

* Browns running back Trent Richardson has what was announced in the press box as a "flank injury." This is otherwise known as a swelling of the abdomen.
