San Francisco 49ers running back Carlos Hyde left yesterday's game with a possible concussion. Hyde was not able to return and sat out the entire second half. However, head coach Jim Tomsula claims he was cleared to return but the team wanted to be cautious with him. Hyde confirmed what his coach said. "I had a concussion evaluation," Hyde said. "Everything is good. I got cleared to come back and play, but coach told me I was not going to come back in. I got hit on the crown of my helmet, so I was dizzy when I got up.
