Martinez had the cast on his right foot removed Monday and has started physical therapy, Evan Woodbery of MLive.com reports.
Martinez was finally able to start physical therapy after having his right foot constrained to a cast for the past couple weeks, marking a milestone in his rehab. The 29-year-old is hoping to return to the Tigers in late April or early May, though there still isn't a firm timetable. "He said he'd let me know how he feels [Tuesday]," said manager Brad Ausmus. Until Martinez is able to return, Mikie Mahtook and Tyler Collins will likely split time in right field.
