The Washington Redskins will have four choices in the new, 12-round National Football League draft, the pick of the litter being a fourth-round selection.

The Redskins also will choose in the 10th, 11th and 12th rounds. All their other picks have been dealt away in trades or transactions with other clubs.

The Redskins will not reveal until the week of the draft - on or about May 1 - where those other choices have been disbursed.

They have previously announced that their No. 1 pick went to St. Louis for defensive tackle Dave Butz; Nos. 2 and 4 to San Diego for safety Bryant Salter (now with the Colts); the No. 7 choice to Houston for tackle Ron Saul, and the No. 8 pick to Kansas City for defensive end John Matuszak (now with Oaskland).

It has been learned that the Redskins' third-round pick also belongs to San Diego. The Redskins sent that choice to the Chargers for defensive end Deacon Jones, who played one season (1974) and then retired. The Redskins also got an undisclosed choice from the Chargers.

The Redskins' sixth-round pick this year went to the Eagles in the trade that sent tackle Manny Sistrunk to Philadelphia for cornerbank Joe Lavender.

The Redskins never announced terms of that trade, but it has been learned they gave up a fifth-round choice in 1978 and a fourth-round choice in 1979 for Lavender.

The Redskins' fifth-and ninth-round picks this year may have been involved in the deal that brought center Ted Fritsch from Atlanta during training camp last year.

The Redskins announced they paid two future draft choices for Fritsch at the time. Neither team will release the numbers involved.

The Redskins' fourth-round pick actually will be Miami's choice. It came in the deal that sent Salter to the Dolphins for safety Jake Scott.

It was originally announced that the Redskin got a No. 2 pick, but that was contingent on Salter signing with Miami. He was released by Miami picked up and released by Seattel and caught on with the Colts late in the 1976 season.

The Redskins' No. 1 priority in the offseason will be to acquire a good pass-rushing defensive lineman, and they will probably use the fourth-round pick to secure one.

"Its a very good year for defensive linemen," said Mike Allman, the Redskins' director of college scouting. "We still could get a good player when we pick."

What did the Redskins get for their picks? Butz won a starting tackle position last year; Salter started two years and Scott started in 1976; Deacon Jones played sparingly in 1974, mostly in obvious passing situations; Saul stated at offensive guard in 1976; Matuszak lasted two weeks in training camp, was cut and picked up by Oakland, where he started on the Super Bowl Championship team and Fritsch handled all placement and punting snaps in 1976, with no bad snaps.
