The San Diego Chargers made several roster changes following the preseason opener.

The Bolts signed DT Kamal Johnson, LB Zack Hodges and LB James Vaughters, waived CB Carrington Byndom, and placed WR Stevie Johnson (knee) and NT Sean Lissemore (shoulder) on the reserve-injured list.

Kamal Johnson is a 6-3, 314-pound defensive tackle who originally signed with the Miami Dolphins in 2014 as an undrafted free agent out of Temple. He spent the entire season on IR after suffering an injury during the preseason. Johnson was a member of the Washington Redskins' practice squad for part of last season.

The 6-3, 246-pound Hodges joined the Indianapolis Colts after going undrafted out of Harvard in 2015. He has also spent time with the Los Angeles Rams. Hodges totaled 26.0 sacks and 41 tackles for loss over his career at Harvard, and was a three-time First Team All-Ivy League selection.

Meanwhile, Vaughters saw time on the practice squad for the Green Bay Packers last season and was with the New England Patriots earlier this offseason. He totaled 139 tackles, 19.0 tackles for loss and 12.5 sacks over four years at Stanford.
