Callahan is out of the lineup for Sunday's game against the Royals.
Javier Baez will get the nod in left field Sunday, but Callahan has emerged as the Tigers' primary option at the position since being called up from Triple-A Toledo a week ago. He has started five of the ensuing six games, going 5-for-17 with one home run, one triple, one double, five RBI and two runs.
