49ers’ Cannon taken off field in ambulance after collision

By The Associated Press

San Francisco 49ers backup running back Trenton Cannon was taken off the field in an ambulance after a scary collision on the opening kickoff in a 30-23 loss at Seattle. Cannon was attempting to make a tackle on DeeJay Dallas when his head hit the leg of a teammate. San Francisco’s training staff immediately ran onto the field and stabilized Cannon’s neck. He was eventually placed on a backboard, loaded onto a stretcher and into an ambulance that was brought onto the field. The 49ers said Cannon had a concussion, was in stable condition at a Seattle area hospital, and would remain overnight for observation.
