Browns offensive tackle Ryan Miller player was taken to the Cleveland Clinic's main campus this evening after being carted off the field during a scary scene at training camp.
Miller suffered a concussion and was released from the hospital tonight, a team spokesman said. Miller is awake, alert and has movement in all four extremities.
In his post-practice news conference, Browns coach Rob Chudzinski said Miller suffered a head injury during one-on-one blocking drills. Chudzinski said specifically said Miller did not injure his neck, and he did not know whether Miller has a concussion.
"Ryan's doing well," Chudzinski said. "He's responsive, and it sounds like things are better at this point. We'll continue to be able to give you updates on that. I plan on visiting Ryan tonight and seing him."
Miller's injury occured at about 4:39 p.m. The Browns originally asked the media not to identify Miller, 24, until his family has been notified. A team spokesman released his name at 5:28 p.m.
The Browns drafted the 6-foot-7, 320-pound Miller last year in the fifth round (No. 160 overall). Miller, who played at the University of Colorado, spent his rookie season as a backup.
Miller fell to the ground during individual drills and remained there until medical personnel immobilized him, strapped him to a board and carted him out of the field house and to an ambulance. He was wearing his helmet when he was carted off.
Browns Pro Bowl left tackle Joe Thomas said Miller was unconscious for a brief time.
"Your heart goes out to him, and you just keep praying and hoping that everything's OK," Thomas said. "It's a great feeling when you hear he is moving his hands and his legs and stuff like that."
The Browns practiced indoors today and closed the session to the public, citing inclement weather. Practice began at 4 p.m. The players wore shoulder pads for the first time during training camp today.
After Miller fell to the ground, some of his teammates continued to work in drills for about two minutes until linebacker Quentin Groves alerted them and coaches about the situation. Then all of the players knelt in prayer and silence.
"We're a family first because we spend more time with these guys than our own families sometimes," Groves said. "So anytime your brother goes down, you just want to get a prayer for him, and make sure everything's all right with him.
“Anytime your brother goes down it’s scary ‘cause you never know. We play this game so hard, so violent. Any moment, this game could be taken away, and that’s the thing I want guys to learn from this. Cherish the moments while you’re out here. Cherish tying your cleats up. Cherish the smell the grass. Cherish snapping that chinstrap on because any moment it can be taken away from you.”
Miller was carted to the ambulance at about 4:45 p.m. The team huddled around Chudzinski and resumed practice and about 4:46 p.m.
By about 5:05 p.m., a team spokesman updated the media on Miller's condition. Chudzinski later stopped practice, had the players huddle around them and told them Miller was OK.
