TODAY, 6:20pm: The Chargers have placed Mebane on the injured reserve, according to ESPN’s Eric Williams (via Twitter).
NOV. 14th, 2:03pm: Brandon Mebane tore his biceps and is out for the season, a source tells Ian Rapoport of NFL.com (on Twitter). 
Mebane signed with the Bolts in free agency this spring. Upon joining the team, he spoke glowingly of the defense and how excited he was to be a part of it.
“I was telling guys, there’s more talent on this defense than in Seattle. If you look at the draft, you’ve got four first-round draft picks. You’ve got five second-round draft picks, all total on defense. In Seattle, we only had two first rounders and one second rounder. Everybody else was pretty much down in the draft or undrafted,” he said in May.
The longtime Seahawks defensive lineman spent his entire career in Seattle before joining San Diego this offseason. From 2007-2015, he missed only 13 games. Now, he’s pretty much going to miss the second half of the 2016 season.
Mebane earned an average rating from Pro Football Focus for his 2015 performance, placing him just inside the top-100 of the league’s interior defenders. This year, however, PFF has Mebane ranked as the 15th best interior defender in the NFL, ahead of notables such as Malik Jackson, Michael Brockers, Stephon Tuitt, Derek Wolfe, and Dominique Easley.
