TALLAHASSEE, Fla. - Florida State had one of the deepest defensive lines in the country.

On Monday, it just got thinner.

The Seminoles announced senior defensive end and preseason All-America Brandon Jenkins will miss the entire 2012 season with a foot injury.

Jenkins injured his left foot after a teammate stepped on it in the 69-3 victory over Murray State.

It was not believed to be serious, but an MRI revealed it is a lisfranc injury.

Jenkins opted to forgo the 2012 NFL Draft to return for his senior season as a Seminole.

He was believed to be an NFL first-round talent.

The FSU standout had 13.5 sacks in 2011 and was two and a half sacks short of third-place all-time in school history.
