BEREA - Courtney Brown passed his physical examination but didn't participate in drills.
Brown has been cleared to practice, but the amount of contact he goes through will be closely monitored.
"It's a step-by-step situation," team president Carmen Policy said. "It's incremental as he shows how he'll be able to handle it."
Brown had microfracture surgery last December after he suffered cartilage damage in a game against New Orleans. He's being counted on to help a defense that's undergoing an overhaul at linebacker.
Coach Butch Davis anticipates having Brown on the practice field Saturday morning when the team practices in full pads for the first time. The plan is to have him go through stages, starting with individual drills.
"He's at the stage that mentally and clinically he's done all he can do until he takes the next step and takes football drills," Davis said. "We'd be foolish to go out there and expect him to be able to scrimmage today or tomorrow."
Defensive tackle Gerard Warren bruised a knee early in practice and was taken for precautionary tests. No further tests are planned, and he should be on the field Saturday.
Cornerback Anthony Henry suffered a minor hamstring injury that sidelined him most of the practice. The injury isn't considered serious.
From the Notebook:
Defensive coordinator Dave Campo has started a practice policy in which one defender wears a yellow jersey throughout practice. The idea is to put pressure on the selected player to be the leader that day. Defensive tackle Orpheus Roye wore the jersey Friday.
The Browns agreed to terms with long snapper Bryan Pittman, who played at the University of Washington. Pittman played for Puget Sound of the Northwest Football League and Arizona of the Arena Football League. He was originally signed on April 9 but was waived May 19.
Butch Davis became perturbed when asked about the seven rookie holdouts. He said he will only answer questions dealing with the players in camp.
