A Cook County (Ill.) probate judge ruled that two grandchildren of the Chicago Bears' founder must sell part of their interest in the team to real estate developers who have tendered an offer for nearly a fifth of the NFL team.

Judge Henry Budzinski said the sale of $17.5 million in Bears stock to Judd Malkin and Neil Bluhm was in the best interest of the estate of the late George (Mugs) Halas Jr., the founder's son.

Two of the Halas children had opposed the sale, calling the offer below the actual value of the stock, which equals about 20 percent of the team. The sale is subject to NBA approval . . .

The Kansas Chiefs fired college scouting director Les Miller, replacing him with Whitey Dovell.

Dovell was an offensive lineman at Maryland and coached the freshman team there in 1952. He was an assistant varsity coach there through 1967, when he became an NFL assistant.

Miller's draft choices got him in trouble. He picked running back Ethan Horton, who was released after two unproductive seasons, and quarterback Todd Blackledge, who likely won't be invited back. To get Blackledge, the Chiefs passed on John Elway and Dan Marino.
