THE SIDELINES : Cowboys Trying to Trade Walker

With few marketable players to use for bargaining to acquire fresh talent, the Dallas Cowboys have tried to trade All-Pro running back Herschel Walker, according to published reports.

Walker rejected a trade Thursday that would have sent him to the Minnesota Vikings for “a slew of draft choices,” officials said.

The Cleveland Browns also expressed interest in trading for Walker, but the running back’s veto of the trade to Minnesota apparently silenced talks with other teams as well.

The Vikings sought Walker’s approval of the trade, even though he does not have a no-trade clause in his contract with the Cowboys, because he has talked frequently about retiring from football.

Browns Coach Bud Carson said today he doubts if Walker will play for Cleveland. However, Browns spokeswoman Francine Lubera said the team is still interested. Browns fullback Kevin Mack has been jailed on a drug conviction.
