Philip Rivers' consecutive starts streak is in jeopardy.

The Los Angeles Chargers quarterback was placed into concussion protocol Monday, coach Anthony Lynn told reporters, one day after the Bolts fell to the Jacksonville Jaguars in overtime.

It's unclear when Rivers suffered the head injury. On his final play of the game, Rivers threw a deep interception to Jags corner A.J. Bouye and then proceeded to deck Bouye out of bounds to prevent a game-winning pick-six. Rivers was not sacked by the self-proclaimed "Sacksonville" defense, but did take five QB hits. Rivers finished with 235 yards, two touchdowns and an interception in the 20-17 loss.

The 35-year-old has not shown up on the injury report this year and has not displayed .concrete signs of physical deterioration
