Washington Redskins General Manager Bobby Beathard foresees trouble if the NFL holds next week's supplementary draft for wide receiver Cris Carter and running back Charles Gladman. Carter, who played for Ohio State, and Gladman, who played for Pittsburgh, petitioned the NFL to hold the draft after they lost their NCAA eligibility for dealing with agents. The NFL acquiesced rather than risk losing a lawsuit.

"I was disappointed to hear we're going to have it for those guys because they don't deserve it," Beathard said. "They should have to wait a year. They broke the rules and now they're being rewarded for it. I think it could open up a can of worms."

Ohio State's coach, Earl Bruce, criticized the draft, too, saying: "To think that somebody could approach any young man today and say 'Hey, I'm going to give you $10,000 a month if you sign with me. If you don't get caught, you've got many dollars in your pocket. If you get caught, all we'll do is put you in the NFL.' . . . Unless we stop those agents, we're in trouble." . . .

The Irwindale City Council approved a $115 million loan to the Los Angeles Raiders as part of an agreement that would move the team to the small industrial center in the eastern San Gabriel Valley. Though the Raiders refused to acknowledge making a deal, Irwindale officials said after Wednesday night's vote that they would travel immediately to Oxnard to sign the agreement with team owner Al Davis. The plan calls for a 65,000-seat stadium in Oxnard 25 miles northeast of Los Angeles . . .

There is a 50-50 chance of another strike by the National Football League Players Association, says Ed Garvey, who headed the union during the players' strike in 1982.
