NFL owners today are expected to approve the creation of five-man developmental squads. The squads will have a lesser impact than if they had been approved earlier, since players placed on injured reserve since the first week of the season are eligible to return to practice.

Only five extra players can practice at a time, so as players on injured reserve return to practice, players from the developmental squad will be cut.

No matter, the Redskins will still sign five players -- offensive lineman Tim Moxley, running back George Searcy, safety Rico Labbe and receivers Paul Smith and Percy Waddle. All five were in camp with the Redskins. Sprained Shoulder May Sideline Williams

The Redskins came out of Sunday's 19-15 victory over the Dallas Cowboys with a long list of bumps and bruises. But it appears the only player, other than quarterback Mark Rypien, who might not play against the Phoenix Cardinals this week is defensive lineman Eric Williams (sprained left shoulder).

"It's awfully sore," trainer Bubba Tyer said. "I think he's going to be okay for Sunday, but I don't know about practice this week. He'll continue taking treatment."

Williams was credited with two tackles after playing a few passing downs. One problem is that Sunday was his 1990 debut. He missed all of training camp until the Redskins acquired him from the Detroit Lions two weeks ago. He has had only one full week of practice.

Defensive end Fred Stokes (dislocated finger) had the most serious of the other injuries, but he probably will practice Wednesday.

Cornerback Alvoid Mays (knee) and linebacker Monte Coleman (hamstring), each of whom sat out the Dallas game, are expected back this week. . . .

The Redskins originally thought tight end John Brandes had a sprained neck, which he did Sunday night. But when he got to Redskin Park Monday morning, it was a swollen and discolored nose that caused him the most pain.

"They think it's broken," Brandes said. "All I know is the guy got me good. He butted me with the helmet and I was feeling like I was going to die. I had a stinger in my neck. My eyes were watering."

The injury occurred during during punt coverage. Brandes said he didn't see who got him, but guessed it was safety Ray Horton.

"He tried to get me two or three times," Brandes said. "I give the guy credit. He got me a good shot." No Bum Rush on Aikman

It has been a decade since the Redskins had a better day rushing the passer than they had Sunday against Dallas's Troy Aikman, whom they sacked eight times. The last time they had eight sacks was Jan. 17, 1988, in the NFC championship game against Minnesota.

The last time the Redskins did better was on Dec. 21, 1980, when they had nine sacks against the St. Louis Cardinals. Coleman had three that day. . . .

With Coleman out Sunday, top draft choice Andre Collins, who had been coming out on passing downs, was given a chance to play in all situations. He responded with a first-rate performance: eight tackles, his first career sack and a pass deflection.

"I liked being in there, but there are still a lot of things I'm not doing well," Collins said. "I still have a tendency to let up on pass coverage things and I've got to correct that. You could say it's all part of being in my first year, but if they have enough faith to put you out there, you've got to make the plays. It's still going to take some time." . . .

When Rypien was hurt, rookie running back Brian Mitchell was elevated to the role of backup quarterback. Mitchell, a quarterback at Southwestern Louisiana, smiled at the possibility.

"I went over and told Stan {Humphries} to stay healthy," Mitchell said. "I know the basic stuff we run, but to go in there and do it might be tough. I'd give it a try."

The Redskins are more concerned with Mitchell holding onto the ball on kickoff returns. He fumbled one in preseason and led off the second half Sunday with another when Bill Bates hit him and Horton recovered.

Mitchell's fumble was the Redskins' first and only turnover of the season.
