Middle linebacker Mike Barrow worked out for athletic trainers on Friday during mini-camp practice and appeared to show good maneuverability on his injured left knee, but team officials cautioned that Barrow's status remains uncertain.
Barrow is not expected to participate in any practices during this weekend's mini-camp. He was supposed to work out for athletic trainers last week, but he had a death in the family and was not available to Redskins Park.
"Obviously, Mike is a concern for us," head coach Joe Gibbs said. "It's something we just have to live through. Today's first workout--he was back. [Director of sports medicine] Bubba Tyer said he looked good.
"We'll continue to work with him. We're going after it pretty hard with him and at some point, we hope he'll be freed up to start practicing."
Barrow, who signed with the Redskins in April 2004, missed all of 2004 due to tendinitis in his knee. This year, if he can get healthy, Barrow is one of several candidates expected to compete for the vacant middle linebacker job.
The Redskins also announced on Friday that the team released defensive lineman Tyler Luebke, a rookie out of Iowa. Luebke was originally signed as an undrafted rookie free agent in late April.
