On Saturday USC scrimmaged with live tackling for the first time this season, and the Trojans did not emerge from the practice session unscathed.

According to the school's website, neither receiver Marqise Lee nor quarterback Max Wittek played in the scrimmage, as both suffered knee injuries.

QB Max Wittek and WR Marqise Lee both suffered knee injuries during practice and sat out the scrimmage.  Lane Kiffin announced that both will have further testing before a diagnosis is announced.  Lee stood and cheered his teammates throughout the scrimmage, while Wittek rested on the trainer's table with ice on his knee.

The good news for USC is that with Lee standing around and cheering his teammates on during the scrimmage, it doesn't sound like the knee injury he suffered was very serious. So odds are the Biletnikoff Award winner who finished with the 2012 season with 1,721 receiving yards and 14 touchdowns won't be missing a lot of time.

The question is how serious Wittek's injury is, as he's expected to be Matt Barkley's replacement at quarterback for the Trojans next season.
