Los Angeles Chargers defensive end Joey Bosa, long considered the best defender on the team, left a 41-22 victory over the Cincinnati Bengals Sunday.
Bosa was being evaluated for a head injury he suffered in the second half as the Chargers attempted to hold off a Bengals rally.
Bosa has battled injuries through much of his career, and usually plays through them. This one was a different story, and the Chargers defense struggled in the third quarter without him.
This season, the 6-foot-6, 280-pound Bosa has 36 solo tackles and 19 assists to go along with 7.
