Rivers hasn’t missed a game since becoming a starter in 2006. A concussion rendered him "questionable" for Week 11 last season, but Rivers hasn't otherwise dealt with a noteworthy injury since his ACL tear in January 2008. His O-line has improved recently as well, ranking 3rd in Football Outsiders' adjusted sack rate for 2017.
