Carter was removed from Friday's game against the Red Sox with right oblique soreness, Shawn McFarland of The Dallas Morning News reports.
Carter made a diving catch in the fourth inning but was replaced on defense when the Rangers took the field in the fifth. The severity of the young outfielder's injury remains unknown, but more outfield reps could be coming for Ezequiel Duran or Michael Helman if Carter has to miss time.
