Chargers star linebacker Denzel Perryman suffered an injury to his LCL and probably needs hamstring surgery as well, Ian Rapoport of NFL.com (on Twitter) hears. The double whammy will land him on injured reserve, ending his season. 
The Chargers have been one of the league’s surprise successes this season and Perryman deserves serious credit for their 7-2 start. Through nine games, the 25-year-old (26 in December) tallied 51 total tackles and an interception. The inside linebacker doesn’t have any sacks, but he is ranked as Pro Football Focus’ 23rd best linebacker on the strength of his pass rush pressure.
Perryman, a second-round pick in 2015, is no stranger to injury. Last year, Perryman started the year on IR and went right back after seven games.
Without Perryman, the Chargers will likely turn to Korey Toomer or Nick Dzubnar in the middle. It also stands to reason that they’ll add a linebacker, especially since Kyzir White is on IR and Chris Landrum is healing up from a hip injury.
Huge loss. They are already thin at inside linebacker, Dzubnar is an absolute joke. For a team that struggles some against the run…. this is a bad loss.
That’s a big blow for that defense. This team has actually surprised me this year and hopefully this doesn’t slow them down because I’d like to see them continue to make some noise in the AFC.
