MINNEAPOLIS -- The Detroit Tigers hoped left-handed starter Daniel Norris would get up to 90 pitches during his second rehab start Sunday afternoon with the Triple-A Toledo Mud Hens.

Instead, Norris failed to make it out of the first inning and left the mound after being visited by the team's athletic trainer.

The Tigers said Norris experienced groin tightness and was removed as a precaution.

Norris faced only six batters. He retired two, walked two and allowed a double and a home run.

Norris went on the disabled list just before the All-Star Break with a strained groin. During his first rehab start with the Mud Hens five days ago, Norris felt discomfort in his quad, but continued pitching.

Matthew Boyd took Norris' place in the starting rotation and started Sunday against the Minnesota Twins, striking out a career-high eight batters.
