Running back Lewis Walker, a 10th-round pick last year from the University of Utah, has been moved to wide receiver by Redskin Coach Joe Gibbs.

Walker missed all of last season after having knee surgery. He participated in Saturday's scrimmage against Baltimore, after which Gibbs made the decision to turn him into a receiver.

"There are a lot of bodies at running back and we thought this would give him the best chance of making the team," Gibbs said. "He's got a rangy body, which you look for in a wide receiver, so I think he can make the switch."

Today marked the first time in camp that the entire squad has practiced. There were no surprises among either the starting offensive or defensive units, although the defensive front four seems certain to undergo changes before the first game.

Coy Bacon and Karl Lorch lined up at the ends and Perry Brooks and Dave Butz were the tackles. Brooks will be pushed hard by Wilbur Young. Bacon is being challenged by Fred Cook and Mat Mendenhall. Rookie Dexter Manley played mostly on the left side, behind Lorch.

Joe Washington and Clarence Harmon formed the starting backfield, although John Riggins is sure to contend for Harmon's fullback spot.

The Redskins lost cornerback Marcene Emmett, a 12th-round 1980 pick getting a second look, on procedural waivers. He was picked up by Tampa Bay. . . Gibbs said the following players had a good performance in the Baltimore scrimmage: linemen Jeff Bostic, Russ Grimm, Jerry Scanlan and Melvin Jones; backs George Ragsdale, Otis Wonsley and Rickey Claitt; quarterbacks Tom Flick and Phil Kessel; middle linebackers Dave Graf and Bill Banks, and safety James Stewart. . . Bostic, Grimm, Phil DuBois, rookie Darryl Grant and Bob Raba are practicing long center snaps while Dan Peiffer, Bostic, Grimm, DuBois and Grant are working on short snaps. Bostic, who handled both jobs admirably last season, is making strides as a center, which will increase his chances of sticking. . . Mendenhall, who has been hampered by a knee injury, had pads on today and is nearing 100 percent. . . Wayne Sevier, the special teams coach, has his punters and field goal kickers running extensively every day. "After this, we'll be candidates for the 1984 Olympic marathon team," said Mark Moseley.
