Norris (oblique) underwent an MRI on Tuesday and will likely be placed on the disabled list, MLB Network's Jon Morosi reports.
Norris went down with a right oblique strain during Monday's game against the Indians and left the game in the third inning. He suffered the same injury last season, which caused him to miss a month of action. The Tigers haven't officially placed him on the disabled list yet, but the club is hoping that he'll be able to come back shortly after the All-Star Break. If Norris ends up on the disabled list, Buck Farmer or Matt Boyd could take his spot in the rotation Saturday against the Blue Jays.
