USC's Marqise Lee leaves practice in a sling

If USC is going to make any noise this season they'll need big seasons from their experienced players and whoever takes over for departed quarterback Matt Barkley will need to step up. Health will also be a key but the Trojans are of to a bad start in that category.

Star receiver Marqise Lee left practice after injury his shoulder and returned shirtless and in a sling.

At some point during practice Friday, the All-American Lee was on the receiving end of a deep pass but landed awkwardly on his right shoulder after contact with a teammate.  Lee was carted off the field by the team’s training staff and was later seen wearing a sling.

The team's medical staff has not given an update at this moment.

Lee, who had 118 catches for 1,721 yards (14.6 yards per catch average) and 14 touchdowns and will need his production if the Trojans are to have any success this season.

His teammates sound confident that Lee will come back sooner than later.

 “Obviously, your heart stops for a second,” quarterback Cody Kessler, who threw the deep ball on which Lee was injured, said. “But Marqise is a tough guy. He’ll be fine.”

Lee might tell you he'll be fine but that'll be up to the doctors. His health is of great importance to whoever takes over at quarterback for the Trojans.
