The Chicago Cubs could be without catcher Miguel Montero for the National League Championship Series, as the 33-year-old continues to deal with back pain that may keep him off the roster for the best-of-seven showdown with the Los Angeles Dodgers, according to Bruce Levine of 670 The Score.

If Montero - who started behind the plate for Game 3 of the NLDS and went 0-for-4 in the series - is unable to go by the time rosters are due Saturday morning, the Cubs may add a 12th pitcher to their NLCS squad in lieu of the ailing two-time All-Star.

Montero, who owns a .519 OPS through 19 career postseason games, dealt with back issues all season and didn't catch a ton down the stretch, starting just 26 games after the All-Star break while splitting time with both Willson Contreras and David Ross. In 86 regular-season games, his fewest since 2008, Montero hit just .216/.327/.357 (85 OPS+) with eight homers and eight doubles.
