Jordan Mason injury update: 49ers RB heads to locker room in Week 8, Isaac Guerendo replaces him

Status update: The 49ers announced just before halftime that Jordan Mason has a shoulder injury and is questionable to return.

The San Francisco 49ers have dealt with significant injury regression in 2024, and they’ve got another one to deal with in Week 8. Running back Jordan Mason has gone to the locker room late in the second quarter. Isaac Guerendo has taken over for him in the 49ers backfield.

Mason appeared to suffer an upper body injury in the first quarter against the Dallas Cowboys. He was down for a couple minutes before heading to the sideline. He kept his helmet on and it seemed like everything was fine when he returned to the game. However, he has since left again and it’s unclear what his status is for the second half.

Mason left the game with six rushes for 18 yards. Guerendo has quickly secured 38 yards on three carries.

More to come.
