A source tells NFL Network that OLB Dwight Freeney sustained a torn quadriceps muscle in Sunday's win over the Cowboys. The Chargers are still trying to determine whether Freeney will land on injured reserve. Regardless, it's a big blow to the Chargers pass rush. Through the first three games, Freeney racked up 13 quarterback hurries, three quarterback hits and a half-sack while playing on 72.3 percent of the snaps. Former first-round pick Larry English is going to have to step up opposite Jarret Johnson.
