Herschel Walker said that he probably could abandon the U.S. Football League for a spot on the Dallas Cowboys, but that he doesn't want to. In an interview with The Atlanta Journal, Walker said he remains loyal to New Jersey Generals owner Donald Trump.

"There are different things I could do, if I wanted to, to get out of the contract," said Walker, who won the 1982 Heisman Trophy at Georgia. "But I really haven't thought about the Cowboys. In the lawsuit the USFL's got (a $1.32 billion antitrust suit against the National Football League), I think they've got a very good case. I think a lot of things are going to happen in the next few months. Really, my job is to help the USFL."

The Cowboys picked Walker in the fourth round of the 1985 NFL draft, just in case he decides to change leagues. Walker's contract with the Generals runs through 1989. . . .

M.J. Duberstein, the research director for the National Football League Players Association, says the league is supressing information about player injuries this season in response to union criticism of artificial turf fields.

Duberstein said NFL statistics showed that the injury rate after eight games this season was 25 percent below the level at the same point in the 1984 season. And the number of injured players listed as "probable" for next week's games has decreased by 40 percent, he said.

"I'm neither a medical practitioner nor a seer, but I do know enough to say that players are not so tough this season that they are not suffering those so-called minor injuries," Duberstein told representatives of the New Jersey Turfgrass Association during a seminar on athletic fields in Atlantic City.

Joe Browne, NFL director of communications, said from his New York office that Duberstein's accusation was "absolutely false" and that the injury reports are for informational purposes, not for the basis for a statistical survey.
