The Washington Redskins gambled last week that three weeks of weight work would end two months of shoulder problems for Fred Stokes. It did, sort of.

Stokes, who missed all four preseason games, played about as much as he would have under the circumstances, and had one of the three sacks against Phoenix Cardinals rookie Timm Rosenbach.

But his shoulder again popped out of place "three or four times" and the Redskins walked away from a big victory with a big worry.

"I'm hopeful I'll be able to keep playing," Stokes said. "That's all I can say. We're going to look at the films and see where my arm was when it popped out. I'm also going to do a lot of praying."

Trainer Bubba Tyer will attempt to tie the harness around Stokes's shoulder a bit tighter and will look at films to see if Stokes is making any peculiar movements that cause the shoulder to pop out.

"There's nothing I can do except keep trying," Stokes said. "It would pop out and then pop back in. I don't like it, but the thought of surgery . . . I don't like the thought of surgery." Green Has Hip Bruise

The Redskins suffered only one other injury of note -- a bruised hip by cornerback Darrell Green. He's expected to play next week in San Francisco against the 49ers . . . Tight end Terry Orr and guard Mark Adickes, both on the 47-man squad, were left off the roster when the Redskins declared their 45-man active roster . . . Chip Lohmiller kicked a 29-yard field goal in the fourth quarter and now has at least one in 21 straight games -- two short of third place on the all-time NFL list . . . Art Monk caught six passes for 60 yards and has now caught at least one pass in 101 straight regular season games . . . Martin Mayhew's two interceptions were the first of his NFL career and his first since he was a sophomore at Florida State in 1985. Milestones

The victory was the Redskins' first opening day shutout since 1973 and, with the 29-0 season-ending win at Seattle last year, gave them consecutive shutouts for the first time since 1955.

Dating back to last season, the Redskins haven't given up a touchdown in 10 quarters. . . .

Besides Cardinals Coach Joe Bugel, who was with Gibbs at the start of his Washington tenure in 1981 through last season, this game included several other coaching connections.

Bugel's replacement as offensive line coach for the Redskins is Jim Hanifan, who was head coach of the St. Louis Cardinals from 1980 to 1985, where his quarterbacks coach was current Redskins assistant Rod Dowhower.

Bugel's top assistant is offensive coordinator Jerry Rhome, who used to be quarterbacks coach under Gibbs in Washington.
