Bosa injured himself in a collision before halftime and went to a secondary medical tent for evaluation. He did not join his teammates on the sidelines after halftime, and the 49ers ruled him out with a concussion in the third quarter.
Bosa collided head-first into the body of teammate DJ Jones as 49ers defenders descended on the Cowboys quarterback Dak Prescott from opposite sides of the field on a pass during the final minutes of the second quarter.
Bosa remained on his back after falling to the turf before finally walking towards the tent and the locker room. His status going forward was not immediately clear. He will have to clear NFL concussion protocol to participate in any football activity in the future.
Bosa, 24, was named to his second Pro Bowl in three NFL seasons for his 2021 campaign. The 2019 Defensive Rookie of the Year led the 49ers with 15.5 sacks this season. He recorded three tackles and a half sack from Prescott before leaving Sunday’s game. The 49ers were leading, 16-7 when Bosa was injured.
