Martinez has been diagnosed with a non-displaced fracture of the radial neck at the right elbow.
The Tigers will send Martinez for a CT scan on Friday to confirm the results of his X-rays. He left Thursday's game after running into the right field wall in the second inning. Mike Aviles took over for Martinez in right, but if this sends him to the DL (which seems like a strong possibility given the nature of the injury), the team could opt to give Steven Moya another look.
