Malcom Floyd was carted off the practice field with a potentially serious right knee injury Monday. Beat writer Michael Gehlken witnessed the injury, and said it "does not look good." Floyd was down on the ground for several minutes, and many of his Chargers teammates gathered around him in prayer. It would be a huge loss for the Chargers who have already lost Danario Alexander for the season to a torn right ACL. Robert Meachem and rookie Keenan Allen may be forced into action this season. We should know more about Floyd's knee Monday evening.
