Major League Baseball umpire Jerry Layne was struck in the side of the head by a broken bat and was forced to leave Friday's contest between the Cincinnati Reds and the Minnesota Twins.

Layne was behind the plate when Devin Mesoraco grounded out for the second out of the fourth inning. Mesoraco's bat splintered and the barrel struck Layne on the left side of his head.

He went sprawling to the ground and training staffs from both teams were out immediately to check on the injured umpire. He left the field under his own power, but was visibly dazed as he walked into the Reds dugout.

The umpires went with a three-man crew for the rest of the game as Bob Davidson took over behind the plate for Layne.
