BBAO: No damage to Sharrif Floyd's knee

We're Black and Blue All Over:

A brief wave of concern floated over Minnesota Vikings training camp Sunday when first-round draft choice Shariff Floyd reported increased soreness in his left knee after what was believed to be a minor injury in Friday night's preseason opener against the Houston Texans.

An MRI was ordered, but according to numerous reports -- including Floyd himself -- the test revealed no serious damage. It's not clear if he will play Friday night against the Buffalo Bills, but the injury is not expected to impact him long-term.

Eventually, Floyd will resume what is expected to be about a 50-50 rotation with veteran starter Kevin Williams at the "under-tackle" position.

  • Did you know that a receiver on the Detroit Lions' roster appeared on the television show "American Ninja Warrior?" I didn't. Kyle Meinke of Mlive.com explains.

  • The Lions were disappointed with their cornerback play in Friday's preseason opener against the New York Jets, according to Chris McCosky of the Detroit News. Coach Jim Schwartz: "There were a couple of plays where we had bad leverage and missed some tackles, and in the secondary that’s critical. You can't do that. There were a couple of plays on third down where they made plays into the strength of our defense. We didn't play physical enough at our corner position when it came to man-to-man coverage."

  • Carlos Monarrez of the Detroit Free Press: "It’s beginning to appear more likely that Detroit Lions safety Louis Delmas won’t play during the exhibition season in order to rest his sore left knee. And that might not make much of a difference in how effective the veteran safety is when the regular season arrives."
