(AP) _ Browns starting quarterback Derek Anderson made an appearance on the practice field today -- his first since suffering a concussion August 18th in a preseason game versus the New York Giants.

He did some throwing at the beginning of practice while wearing his helmet, and left the field once team drills began.

Brady Quinn again took snaps with the first-team offense and is expected to start Thursday night in the preseason finale against the Chicago Bears. Coach Romeo Crennel says its unlikely Anderson would play.

Anderson is one of six starters who didn't play Saturday against the Detroit Lions and aren't expected to play Thursday.

Crennel says he expects that all of them will be back at practice next Monday to prepare for the September 7th season opener against Dallas.

Cleveland Browns wide receiver Joe Jurevicius will miss the first six weeks of the regular season while he recovers from knee surgery.

The Browns placed Jurevicius on the physically unable to perform list today.

Jurevicius had swelling and discomfort in his right knee related to a previous operation and needed another procedure in June to further clean it out.

After the sixth week of the season, the Browns have three weeks to allow Jurevicius to start practicing. Once he begins practicing, the Browns will have another three weeks to make a decision on his roster status.

Jurevicius had 50 catches for 614 yards and three touchdowns last season. He was expected to have a reduced role this season as the No. 3 receiver behind Braylon Edwards and Donte' Stallworth.
