Jeremy Maclin

Maclin tore the ACL in his right knee during practice Saturday and will miss the season. It's the same injury he suffered at Missouri four years before the Philadelphia Eagles drafted him in the first round in 2010. Maclin is entering the final year of his rookie contract, and was set to cash in with a breakout season in new coach Chip Kelly's high-octane offense.

Maclin went down at the end of a non-contact drill and appeared to be in pain while he was on the ground for several minutes. He was helped onto the cart and needed assistance getting off it and going into the team's practice facility. "I was devastated," he said. "It wasn't the fact that it hurt, it was the fact that I knew what happened so I was emotional, knowing what was at stake."
