Calhoun reached on an error to load the bases for the Angels and then went from first to third on Andrelton Simmons’ two-run double, which gave the Halos a 6-1 lead. Shortly after he reached third, however, trainer Adam Nevala came out to check on Calhoun, who subsequently left the game.
Shane Robinson replaced Calhoun on the basepaths and stayed in to play right field in the bottom of the third.
The 29-year-old outfielder also ran into the right-field wall while attempting to make a catch on Kevin Pillar’s fly ball that went foul in the second inning.
Calhoun entered Sunday batting .232 with a .680 OPS, 13 home runs and 45 RBIs this season.
