Bill Brundige, one of the Redskins' most valuable defensive linemen, will undergo surgery today to repair his injured left foot and will be lost to the team for the 1978 season.

"I've just had so much pain with it. I could not do anything," Brundige said from Sibley Hospital, where team physician Stanford Lavine will perform the surgery this morning.

Brundige suffered a severely sprained foot last year in a regular-season game against the Green Bay Packers at RFK Stadium on Nov. 21 and came back to play in pain two weeks later against Buffalo and the following week against St. Louis.

He was on crutches the day before the Cardinal game. The injury forced him to miss the season finale against Los Angeles, and will cost him a chance to play for his friend and for-until 1979.

A team spokesman said Brundige has a severe sprain of the first metatarsal joint in his left foot and will undergo a bone graft to remove painful spurs.

The Redskins suspected throughout the off season that Brundige might not be available and Pardee said yesterday, "I think we're in pretty good shape for defensive linemen. That's one of the reasons we wanted Coy Bacon (recently) acquired from the initial approach was to see if he could get by without the operation.

"It's something that won't correct itself. But Bill is still young (he will turn 30 in November). The rehabilitation will be critical."

Brundige recently signed a three-year contract with the Redskins, and said yesterday he fully intends to play again. "You know I originally wanted to play for Jack when we went to the World Football League in 1974," he said. "I've always respected him and I'd love to play for him.

"I've played eight years already and that's not bad, unless you look at a guy like (Ron) McDole (an 18-year man). But he's a freak."

Brundige was asked why he tried to play last season after suffering the initial injury, particularly in the St. Louis game on a day when temperatures were below zero and the Busch Stadium field was concrete hard.

"Well, I just thought every game was that important for a playoff spot, and there was nobody else. There was a lot of pressure put on me, not so much to make me play, but that if I could. I was really needed by the team. I felt that responsibility, everyone on the team felt it. So you did what you had to do.

"If I had known we weren't going to make the playoffs even though we won all those games, obviously I wouldn't have done it, because it really doesn't mean a thing. But how do you know that then? No, I don't blame anybody, I'm just sorry I'll have to miss the year.

"I had hoped to be able to come into camp and try and get into some kind of shape where I could work into it slowly. But it got to the point where I couldn't jog, I couldn't play tennis, I had pain when I walked. I just hope the operation lets me do the kind of things I want to do.

Elsewhere on the medical front, running back Tommy Reamon was sent back to Washington to have a fractured thumb placed in a cast. Reamon, a second-year man who once was the WFL's leading ground gainer, suffered the injury in practice Monday.

He returned to camp late yesterday afternoon and probably will be held out of today's sessions. Pardee said Reamon would be able to play with the injury, and probably will see action Saturday in Annapolis during a rookie scrimmage against the Colts.

There was painful news yesterday for seven other players in camp, as Pardee made his first squad cuts.

The Redskins began rookie week overloaded at wide receiver, and five of the cuts came at that position: Charlie Nash of Arizona, Billy Lefear, a five-year pro-from Henderson State; Jimmy Raglon of Texas Southern, Dwight Allen of Bethune-Cookman and Cleo Montgomery of Abilene Christian.

Also waived were tight end Skip Chase of Towson State and cornerback Billy Woods of Georgia.

Bart Buetow, an offensive lineman from Minnesota, left camp and was trimmed from the roster . . . Wide receiver Brian Fryer, the Canadian swifty, made some marvelous catches on deep patterns during afternoon 7-on-7 drills . . . Chris Tormey, a free-agent linebacker from Idaho, sprained his ankle Monday and probably will miss several daus of practice . . . Larry Franklin, speedy receiver from Jackson State caught a long touchdown pass in the morning practice and paid for it when he pulled up with a slight hamstring problem . . . Pardee said he hoped to work a bit on the 34 defense (three linemen, four linebackers) in practice today, even if he only has five healthy-and very tired-linebackers in camp.
