In order to make room for Worthington on the 90-man roster, the Chargers waived/injured defensive end Damik Scafe with a hip issue.
At 6-foot-5 and 318 pounds, Worthington spent the last three years with the Washington Redskins, but was released by that team after the first preseason game. Worthington totaled three tackles in six games in 2012 for Washington. But he spent all of 2013 on the injured reserve list after suffering a torn biceps tendon during offseason workouts.
Worthington was originally a seventh-round pick by the Pittsburgh Steelers in the 2010 draft. He was let go during final roster cuts, spending some time on Pittsburgh's practice squad. After being let go by the Steelers, Worthington signed with Tampa Bay's practice squad in November 2010.
The Buccaneers released Worthington in August of 2011, and he was claimed off of waivers by Washington.
Collegiately, Worthington started 35 games at Ohio State, finishing with 103 career tackles, 12 tackles for loss and four sacks. He was named honorable mention All-Big Ten his senior season.
