Guerrero scored on the play but didn't come out to play defense the following inning. Charles McAdoo replaced him at first base.

Blue Jays manager John Schneider said Guerrero is in concussion protocol after experiencing "a bit of a headache," according to MLB.com's Keegan Matheson.

"You've always got to be careful. We'll see how he wakes up tomorrow," Schneider added.

Guerrero is in the midst of a down year in which he's slashed .263/.337/.356 with seven home runs and 47 RBIs in 115 games.
