BEREA, Ohio -- The Cleveland Browns wrapped up another two-a-day Friday during their mandatory minicamp.
Here are several notes and observations:
Browns quarterback Derek Anderson was seen limping during the afternoon practice and was held out of team drills. Anderson wore a sleeve over his right calf, which hints that he suffered a right leg injury at some point Friday. Quarterbacks Brady Quinn and Brett Ratliff took the majority of the snaps in the second session while Anderson watched from the sidelines.
The competition on the offensive line is heating up. Rookie first-round pick Alex Mack played exclusively with the first team Friday morning. Incumbent starter Hank Fraley has played mostly with the starters in the practices open to the media and did so again in the evening. But the first session may be an early sign that the rookie is starting to close some ground on the veteran. Also, left guard Eric Steinbach practiced with the second team behind Rex Hadnot. Browns coach Eric Mangini says he doesn't have a timetable on determining his starting five up front.
"Once we determine which five we're going to go with, then we will settle," Mangini said. "But even at that point, we're going to have to have those guys be able to work other spots, because there's the possibility of injuries and the possibility of moving things around."
Cleveland's projected starting tight end, Robert Royal, had a tough day at the office Friday. He had three drops in the morning practice.
Backup tailback Jerome Harrison says he is working hard on his blitz pickups, because that is part of what kept him off the field the past three seasons. Listed at 5 feet 9 inches tall, weighing 205 pounds, Harrison struggled taking on hard-charging linebackers on third downs.
"It's a knock on smaller backs," Harrison said. "But it's something you got to get over. It's part of life. I always can get better. I wasn't asked to do it in college."
