Cowboys' Dak Prescott: Picks up shoulder strain

Prescott (ankle) was diagnosed with a strained right shoulder after undergoing an MRI on Wednesday, Calvin Watkins of The Dallas Morning News reports.

Prescott was removed from Wednesday's practice due to a sore arm, and the nature of the issue now is known. After practicing without restrictions in training camp to date while working back from a surgically repaired ankle, he's now considered day-to-day, with eight days to go until the Cowboys' first preseason game Aug. 5 against the Steelers. The time away from the field can't hurt as he continues to put his severe ankle injury from Week 5 of last season further in the rear-view mirror. There's an expectation from Prescott himself that he'll get into game action before Week 1 of the coming campaign, which will be the final test of his recovery.
