COLUMBIA, S.C. (AP) - People familiar with the decision say injured South Carolina running back Marcus Lattimore will enter the NFL draft.

One person said Monday that Lattimore is expected to announce his decision later this week. The people spoke with The Associated Press on condition of anonymity because there has not been an official announcement of Lattimore's decision.

The running back suffered a horrific injury to his right knee against Tennessee on Oct. 27. Doctors say Lattimore had successful surgery to repair several ligaments on Nov. 2.

Lattimore injured his left knee in 2011 as a sophomore. He rushed for 662 yards and 11 touchdowns this season, both team highs. He is South Carolina's career leader with 41 touchdowns.
