Former University of South Carolina star running back Marcus Lattimore is retiring from the National Football League saying he will return to USC to finish out his degree.
The announcement came just days after Lattimore began practicing with the San Francisco 49ers. The 49ers drafted Lattimore in the fourth round of the 2013 daft and placed him on the non-football injury list for most of his NFL career.
He spent his time rehabbing a knee injury he sustained in 2012, during the second quarter of the game against Tennessee.
"As soon as I went to stabilize it, he had dislocated his knee and so his knee actually went back into place before I touched it," said head athletic trainer Clint Haggard.
The injury he sustained led to a fall from a likely first round draft pick. Lattimore ranked sixth in school history with 2,677 career rushing yards and is first in total touchdowns with 41.
Head Coach Steve Spurrier says he reached out to Lattimore and told him he is always welcome back at South Carolina.
"He has a home back here in Columbia at the University of South Carolina and he knows that, so hopefully he will be back soon," said Spurrier.
Lattimore is expected to return to class at USC during the spring of 2015 to finish his degree in public health.
