Martinez was removed from the second game of Friday's doubleheader against the Tigers after colliding with teammate Brayan Rocchio in shallow left field in the top of the fourth inning, Tim Stebbins of MLB.com reports.
Rocchio made the catch and both players were able to walk off under their own power, but Martinez was lifted before the top of the fifth. Nathaniel Lowe replaced Martinez in the game, pushing David Fry from first base out to left field.
