Los Angeles Chargers defensive end Joey Bosa left early in Sunday's game against the Bengals in Cincinnati and was being evaluated for a head injury.
Bosa left the field for the locker room midway through the first quarter, as the Chargers were building a healthy 16-0 lead over the opening 15 minutes. It was unclear when the injury occurred or what the severity might be.
Bosa, 26, had multiple concussions last year. The three-time Pro Bowler ultimately missed four games in 2020.
Prior to Sunday's game, Bosa had 7.5 sacks, 36 tackles and four forced fumbles for the Chargers in 11 contests.
