Ryan Miller, a guard who was a 2012 draft pick of the Cleveland Browns from the University of Colorado, was taken from Saturday's practice by ambulance to the Cleveland Clinic.
Miller was carted off the field and transported by ambulance to the hospital with an undisclosed injury.
The Browns initially did not release his name until family had been notified of the injury.
UPDATE: Miller suffered a concussion in one-on-on drills and could be released from the hospital tonight.
