TAMPA, Fla. (AP) _ Los Angeles goalkeeper Kevin Hartman sustained a concussion in the first half of the Galaxy's 1-0 playoff victory over Tampa Bay on Thursday night.

``They're going to take him to the hospital just to make sure here is nothing serious,'' Galaxy coach Sigi Schmid said. ``He had a concussion in January when he was training in Holland. We just want to make sure it's nothing more serious.''

Hartman appeared to hit his head against the goal post after landing on the ground following a shot by Josh Keller in the 38th minute. Tampa Bay's Steve Ralston also collided with Hartman early in the half during a goalmouth scramble.

``Sometimes, players try and have to much valor at the wrong times,'' Schmid said. ``Kevin was very honest. He said felt a little dizzy and wasn't able to concentrate.''

Hartman was replaced by Matt Reis.
