The Cubs placed All-Star catcher Willson Contreras on the 10-day injured list with a right hamstring strain. Catcher Taylor Davis was recalled from Triple-A Iowa.
Contreras was injured during Saturday's game. After hitting a fly ball, he ran two steps toward first base before reaching back and grabbing his right leg.
He is scheduled to undergo an MRI on Monday to determine how long he's likely to be sidelined.
Kris Bryant is dealing with a sore knee, but Joe Maddon said he was held out of the lineup simply for a day of rest.
