Posted by ESPN.com's Bill Williamson

The Chargers have replaced Pro Bowl linebacker Shawne Merriman's spot on the roster with linebacker Antwan Applewhite. He was on the San Diego practice squad.

Merriman was placed on injured reserve and he will have season-ending reconstructive surgery on his left knee.

Applewhite, a San Diego State product, was on the Chargers' practice squad for a portion of last season as well. San Diego also added linebacker Eric Bakhtiari to the practice squad. He was cut by San Diego on Aug. 30.
