San Francisco 49ers quarterback Alex Smith was diagnosed with a concussion after Sunday’s overtime loss to the Dallas Cowboys.
It’s not clear at what point during the game the concussion happened. Under league rules players are supposed to be pulled from the game as soon as they suffer a concussion, but apparently neither Smith nor the 49ers knew it had happened until after the game. The 49ers say Smith showed no signs of a concussion during the game.
Smith has already been cleared to return and was a full participant in practice today.
San Francisco coach Jim Harbaugh described Smith today as a “tough son of a gun” and said he’s pleased with Smith’s performance.
