Blue Jays pitcher J.A. Happ was hit in the head by a line drive and taken off the field on a stretcher during Toronto’s 6-4 win over the Tampa Bay Rays on Tuesday night.

In a frightening scene at Tropicana Field, Desmond Jennings’ second-inning liner caromed squarely off the left side of Happ’s head in a loud “thwack!”

The ball went all the way into the bullpen in foul territory halfway down the right-field line.Happ dropped face down at the front of the mound, holding his head with his glove and bare hand.

Happ was taken to a hospital for tests but the Blue Jays had no update on his condition immediately after the game, manager John Gibbons said.

Happ was released from the hospital Friday morning.
