An NFL exhibition game scheduled for Aug. 3 at London's Wembley Stadium between the Super Bowl champion Chicago Bears and the Dallas Cowboys may be canceled because of the Libyan situation, organizers said yesterday.

The NFL teams are concerned about the safety of their squads in the wake of last week's U.S. air raid on Tripoli and the fear of reprisals against Americans in Europe.

Wembley spokesman Martin Corrie said a decision had not been reached but that security was "one of the first things discussed."

NFL spokesman Dick Maxwell said the league expected the game to be played. . . .

Walter Murray from the University of Hawaii, a possible first-round pick in Tuesday's NFL draft, was charged with bribery Thursday in Honolulu. Murray, who broke numerous school records while playing wide receiver at Hawaii, was later freed on $1,000 bail.

Last fall, Murray offered a police officer football tickets to avert a traffic citation, police said. Murray said it was "just a joke." . . .

Two former and two current Dallas Cowboys have filed suit against their agent, alleging he defrauded them of about $200,000 in bogus real estate investments.

Cowboys Bill Bates and Jeff Rohrer and former Cowboys Steve Wilson (now with Denver) and Anthony Dickerson (now with Buffalo) filed the suit in Dallas County District Court against agent Joe Courrege.

"I haven't defrauded anyone," said Courrege, who represents about 25 NFL players.
