Lucroy left the game in the top of the seventh inning of Milwaukee's game against the Reds after taking a foul ball off his foot. He was replaced in the game by Martin Maldonado, and minor league catcher Juan Centeno will take his place on the active roster, the team announced.
Lucroy led all National League position players in Wins Above Replacement last year, according to ESPN Stats & Info. The 28-year-old hit .301/.373/.465 last year with 13 homers and 69 RBIs in 2014, finishing fourth in the NL MVP voting, but was off to a slow start in '15, with just seven hits in his first 45 at-bats.
Lucroy's injury is the second major setback for the Brewers this season. On Friday, Milwaukee placed outfielder Carlos Gomez on the DL with a hamstring injury. Second baseman Scooter Gennett could also see time on the DL after a cut he sustained in the shower on Sunday required several stitches in his hand.
With the 6–1 loss to Cincinnati on Monday, the Brewers are now 2–11 to start the 2015 season. Milwaukee will face the Reds on Tuesday in the second game of their series at Miller Park.
