SAN DIEGO – Chargers linebacker Andrew Gachkar was a surprise addition to San Diego’s injury report on Wednesday.

One of San Diego’s core special-teams players, Gachkar earned more playing time in sub packages on defense with his improved play. Gachkar scored his first touchdown since high school against the St. Louis Rams on Sunday, scooping up a Shaun Hill fumble created on a sack by Corey Liuget and rumbling 13 yards for a score.

Along with Gachkar, defensive tackle Ryan Carrethers (elbow) and outside linebacker Dwight Freeney (rest) did not practice. Running back Ryan Mathews (shoulder), receiver Eddie Royal (toe) and safety Jahleel Addae (concussion) were full participants in practice.

The Chargers also announced the team added center Jeff Baca to the practice squad. Baca will wear No. 62.
