Redskins tackle Ed Simmons received a bit of good news yesterday when doctors performed an arthroscopic exam of his right knee and decided no reconstructive work was necessary and that he should have a complete recovery.

But there is no hope he'll return this season. Team doctors and trainer Bubba Tyer estimate Simmons will need about six weeks to rehabilitate his knee. That means he should be 100 percent when offseason workouts begin in the spring, but his 1990 season ended when he was injured near the end of Sunday's 10-9 victory over Chicago.

Still, there had been some fear Simmons would need a complete reconstruction of the knee. Instead he has a partial tear of the anterior cruciate ligament, stretched fibers around the posterior cruciate ligament and a stretched medial collateral ligament. An old piece of torn cartilage also was discovered.

Lineman Moxley Re-Signed

The Redskins signed a second offensive lineman in as many days yesterday when rookie safety Rico Labbe (Carroll High School) was cut from the practice squad and ninth-round draft choice Tim Moxley was brought back.

A day earlier, they claimed Scott Beavers off waivers from the Denver Broncos. He's on the 47-man roster, but will be on the two-man inactive squad for games.

The moves come at a time the team needs more linemen for practices. Simmons is out for the season, and Russ Grimm, Mark May and Ray Brown have been slowed by injuries the last two weeks.

Moxley is interesting because he's a classic Redskins offensive lineman at 6 feet 7, 320 pounds. He probably never would been have cut if rules regarding practice squads were looser, and the Redskins still believe he can play in the NFL.

"We liked him a lot," Gibbs said. "It was just that with all our linemen, it was impossible to keep him."

Labbe was a fourth-round choice last spring. He was waived on Sept. 3 in the final roster cutdown, then re-signed when practice squads were brought back on Oct. 3.

Union Briefs

The Redskins had a post-practice meeting with officials of the National Football League Players Association to be briefed on the continuing legal battles between the association and the owners.

"We're meeting with every team during the season," said Doug Allen, assistant director of the NFLPA. "Players want to know what's happening since the last time we met and what the issues are."
