A fan at Fenway Park was injured by a foul ball during a game Wednesday night, the latest in a series of crowd accidents this season at the century-old stadium.

The man was hit in the first inning by a foul off the bat of Toronto slugger Josh Donaldson, and there was a brief delay as the Blue Jays played the Boston Red Sox. The fan returned to his seat an inning later with what appeared to be an ice pack he was holding on his left shoulder.

The fan was sitting four rows from the field when he was struck and Donaldson looked over to see if the man was OK.
