Fooch's update: Carlos Hyde was cleared to return to the game, per sideline reporter Laura Okmin. He has not returned, and given the score, I am not surprised.
The San Francisco 49ers are likely going to play the remainder of the second half without running back Carlos Hyde. The running back went to the locker room with trainers in the third quarter. He is being evaluated for a head injury, and is questionable to return. It would appear to have happened when Mike Mitchell got a big hit on him earlier in the quarter, but we'll keep an eye out for more information.
Hyde rushed 14 times for 43 yards and a fumble prior to the injury. He also had four receptions for 18 yards. Hyde departed earlier in the game with a leg injury, but returned from that. He took a low shot from a Steelers helmet, and seemed a bit gimpy from that. This injury though would appear to be completely unrelated.
Jarryd Hayne took for Hyde after the leg injury, but Mike Davis appeared to be the guy getting all the snaps once Hyde left with the head injury. They used Davis down near the goal line, including a fourth down conversion that set up a first and goal. The 49ers remain down 29-3 in the fourth quarter.
