Chargers quarterback Philip Rivers will play on Sunday against the Buffalo Bills after clearing the NFL’s concussion protocol program Friday afternoon. Rivers, who has started 194 consecutive regular-season and playoff games dating back to 2006, the fourth-longest streak for quarterbacks in NFL history, was a full participant in practice for a second straight day on Friday. Coach Anthony Lynn said Rivers looked "fine, normal, like himself." The 35-year-old quarterback, who is married with eight children and who has played games with a torn-knee ligament, a bulging disk in his lower back and a bruised rib cage, was cleared to play by an independent neurological consultant.
