MILWAUKEE - Milwaukee Brewers All-Star catcher Jonathan Lucroy could miss four to six weeks with a fractured big left toe.

Lucroy got hurt after during Monday's 6-1 loss to Cincinnati when a foul tip caromed off his foot. He was placed on the 15-day disabled list immediately after the game.

The injury news only got worse on Tuesday for struggling Milwaukee.

Manager Ron Roenicke said Tuesday starting second baseman Scooter Gennett was placed on the DL after cutting his left hand in the shower after Sunday's game in Pittsburgh. The move was retroactive to Monday.

The Brewers called up utility man Elian Herrera from Triple-A Colorado Springs to replace Gennett. Minor league reliever Brandon Kintzler was designated for assignment.

Milwaukee had the worst record in the majors at 2-11 going into Tuesday's game against the Reds.

The offence was struggling even before the injuries to Lucroy and Gennett. Outfielder Carlos Gomez is on the disabled list with a strained right hamstring.

Tuesday's patchwork lineup had Herrera playing second base and Jason Rogers playing third to spell the slumping Aramis Ramirez.

"It's hard, but like I said we weren't winning and scoring runs when we had everybody," Roenicke said. "So hopefully some of the different guys I put in there today, those guys are hot."

Martin Maldonado figures to get the bulk of the starts behind the plate while Lucroy is out. Juan Centeno was called up from Triple-A on Monday night to take Lucroy's spot.
