Rockies manager Bud Black said that Bryant isn't in the lineup Monday against the Reds due to a sore back, Thomas Harding of MLB.com reports.
Black noted that Bryant is sore after the 32-year-old made a twisting catch in the outfield during Sunday's 4-0 loss to the Dodgers. Bryant is consulting with doctors and trainers and is considered day-to-day for now. With Bryant on the bench Monday, Jacob Stallings will step in as the Rockies' designated hitter.
