Los Angeles Chargers sign third-round pick Justin Jones

The Los Angeles Chargers signed third-round draft pick, defensive tackle Justin Jones, to a four-year contract Saturday.

That leaves only first-round pick, safety Derwin James, as the team's only unsigned draftee.

Jones had 108 tackles, 22.5 tackles for loss and 8.5 sacks in 34 games at North Carolina State.

Jones is competing for playing time with Brandon Mebane, Darius Philon and Damion Square. The Chargers will need help up front early in the season with Corey Liuget serving a suspension the first four weeks.
