Mead has a nondisplaced left wrist fracture and will be reimaged in four weeks, Ian Browne of MLB.com reports.
Mead was placed on the 10-day injured list Wednesday after suffering the injury when he was hit by a pitch Monday night against the Athletics. The 25-year-old is anticipated to be sidelined for roughly 6-to-8 weeks, with Thursday's news giving him a chance to hit the front end of that timeline.
