The Dallas Cowboys, admitting, in the words of Coach Tom Landry, that they were taking a "calculated risk," traded linebacker Anthony Dickerson to the Buffalo Bills yesterday.

"Sure, I'm a little upset about it," said Dickerson, a six-year veteran who guessed what was about to happen when he did not play Monday night in the Cowboys' 15-13 preseason victory over Chicago.

Dickerson told the Associated Press, "I'm the best linebacker they've got here and I hate to go, but I can tell you one thing: I'm shifting my loyalty to the Bills right now."

Team sources told the AP the Cowboys would receive future draft choices.

"We had to make a decision based on putting together a team trying to get back into the playoffs," said Landry. "We decided we have to try to bring in young players."

To get down to the 50-player limit, the Cowboys cut rookies Loyal Proffitt, a quarterback from Abilene Christian; punter Bryan Wagner; veteran wide receiver Kirk Phillips; offensive guard Syd Kitson; offensive tackle John Hunt; running back Norm Granger, and defensive end Chris Arendt.

Offensive guard Brian Baldinger and fullback Todd Fowler were placed on injured reserve.

*Rams: Jack Youngblood, a standout at defensive end for the Los Angeles Rams since 1971, said he is retiring because he doesn't believe he can live up to standards he set for himself.

Youngblood, 35, was a first-round draft choice by the Rams after he completed his college career at Florida, and has been a starter in each of his 14 NFL seasons.

He was selected as an all-pro performer six times and played in seven Pro Bowls.

*Giants: Released veteran punter Dave Jennings, a move Coach Bill Parcells described as "the most difficult cut I've had to make as a head coach."

Jennings, 33, a four-time Pro Bowl selection, lost his job to former USFL punter Sean Landeta after two subpar seasons. At an emotional news conference, Jennings said he is not bitter and that he intends to punt for another team this year.

*Buccaneers: Rookie Donald Igwebuike became Tampa Bay's placekicker when Obed Ariri, a childhood friend of Igwebuike in Nigeria, was cut.

Ariri, who set club records for points scored (95) and field goals made (19) in 1984, was one of three players released as Coach Leeman Bennett reduced his roster to 50.

The Buccaneers attempted only one field goal in three preseason games -- a successful 31-yarder by Ariri -- so Bennett's decision apparently was based largely on kickoffs.

Ariri had five kicks returned an average of 18.4 yards. Igwebuike's four kicks were returned an average of nine yards, partly because two of them were put into the end zone and were unreturnable.

*Dolphins: Tight end Dan Johnson, who arrived at Miami's training camp Monday, was knocked out of action for at least four weeks yesterday in an unusual manner. He had an appendectomy.

Johnson, a three-year veteran, was rushed to a hospital after complaining of abdominal pains.
