BEREA, Ohio -- Browns offensive tackle Ryan Miller was being treated at a hospital after being carted off the field during practice.
Miller, who is in his second season with Cleveland, was taken to the Cleveland Clinic by ambulance. A team spokesman said Miller was "awake, alert and has movement in all four extremities." The team hadn't released any other information about Miller's injury or illness.

Cleveland's players, wearing shoulder pads for the first time in training camp, were doing one-on-one drills inside the team's indoor facility when Miller wound up on the turf at 4:39 p.m. It's not known if the 6-foot-7, 320-pounder was injured or collapsed.
As medical personnel rushed to Miller, the music inside the field house was turned off and several players took a knee. After Miller was immobilized and strapped to a backboard, the entire Browns team and coaching staff huddled around the player and prayed.
After Miller was wheeled from the facility to be taken to the downtown hospital, the Browns continued their practice, which was moved indoors because of bad weather and closed to the public.
Miller was drafted by the Browns in the fifth round in 2012 out of Colorado. He appeared in eight games as a rookie, and got extended time in the fourth quarter of the season finale at Pittsburgh after John Greco sustained a knee injury.
Miller was a four-year letter winner at Colorado, setting a school record with 48 career starts. He missed just two offensive plays over his final three seasons.
