BOSTON -- A fan at Fenway Park has been taken away on a stretcher after flipping over backward trying to catch a foul ball.

The accident occurred Wednesday during the seventh inning of a game between the New York Yankees and Boston Red Sox.

The fan was in the last row of the lower box seats, and landed on the concrete walkway that separates the lower and upper boxes. A witness said there was a bloody shirt on the concrete.
