Rangers manager Bruce Bochy said Langford is out of the lineup for Sunday's game against the Red Sox due to back tightness, Shawn McFarland of The Dallas Morning News reports.
It's the second straight game on the bench for Langford, though Bochy said that the Rangers have "minimal" concern about the injury, per Jeff Wilson of RangersToday.com. The 22-year-old could be available off the bench Sunday, but the Rangers will likely attempt to avoid using him to provide two full days of rest.
