The Chicago Cubs have been bitten by the injury bug once again, as catcher Miguel Montero has been placed on the 15-day disabled list.

Montero, who is batting .208 with a home run and six RBI for the Cubs so far this season, has been dealing with back stiffness all week long, and the move will put him on the DL retroactive to Monday, according to the club.

Tim Federowicz will join the Cubs to back-up catcher David Ross in Montero’s absence. Federowicz, who hasn’t caught in an MLB game since 2014, has batted .303 with a home run and six RBI for the Cubs’ triple-A affiliate in Des Moines so far this season. He also has coaxed six walks to give himself a solid .415 on-base percentage during his stint in the minors.

If Federowicz can’t join the Cubs in time for Thursday’s game against the Milwaukee Brewers, Montero will remain on the roster as an emergency catcher. Javier Baez could also be tapped to play the position if Ross is injured during the contest, with first pitch scheduled at 1:20 p.m.
