Mike Fiers likely won't throw for at least another four weeks after an injection for his sprained right elbow.
Bob Melvin said Thursday that Fiers, who last pitched May 6, won't need surgery after he felt discomfort when trying to resume throwing this week.
"Nothing structural as far as needing surgery at this point, but he will get a PRP injection and then probably no-throw for up to four weeks," Melvin said. "So it's going to be a while before he even starts playing catch again."
Melvin said the Oakland Athletics still believe there is a possibility for the 36-year-old Fiers to pitch again this season.
