Maggie Herger told the San Jose Mercury News (http://bit.ly/uzIOsB ) that a drunken Sharks fan hit her in the head during Wednesday's game between the Sharks and Vancouver Canucks.
Herger, of Discovery Bay, says she suffered a concussion and was taken away in an ambulance.
But according to the Sharks, the other fan told police and arena staff the contact was accidental and occurred during the celebration of a Sharks goal.
Police say they have taken statements from witnesses but don't expect to assign detectives to the case for at least a few days, and nobody has been arrested.
