Home-plate umpire Kerwin Danley suffered a mild concussion after being struck by a broken bat in Toronto on Tuesday night.

He was hit on the side of the head by Texas infielder Hank Blalock's broken bat in the sixth inning.

"It didn't sound good. It was a pretty loud thump," said Rod Barajas, who was catching at the time. "I was just hoping he'd get right back up and kind of shake it off, but his eyes were closed. He wasn't making any movements and he wasn't talking. That's a bad sign."

During a 10-minute delay, a neck brace was carefully placed around the umpire's head, and he was placed on a stretcher and taken off the field on a medical cart.
