Head coach Kyle Shanahan had an update on RB Trenton Cannon, who left Sunday’s game in an ambulance.

49ers head coach Kyle Shanahan had an update on running back Trenton Cannon who was taken off the field in an ambulance after sustaining a head injury on the opening kickoff of Sunday’s loss to the Seahawks.

Cannon suffered a concussion, but no additional head or neck injuries according to Shanahan. Overall it’s good news that there’s no further damage after Cannon was hit in the head and then hit in a way that bent his neck awkwardly as he went down while making a tackle on the opening kickoff.

The 27-year-old running back will stay in a Seattle-area hospital overnight for further evaluation.
