William (The Refrigerator) Perry's bulk was a favorite topic at the opening session of the Chicago Bears' training camp in Platteville, Wis., with Coach Mike Ditka announcing that the lineman had tipped the scales at 325 at the team's weigh-in. The Bears had asked him to report at 300.

But the coach said he wasn't worried about Perry's weight, that he was sure he would get it down before training camp ends.

"He worked out religiously until a week ago, and then he went home to South Carolina," Ditka said. "That's usually a catastrophe. The chicken population of South Carolina goes down measurably."

The Bears also announced the signing of defensive end Al Harris, who sat out last year's championship season in a contract dispute . . .

Philadelphia Eagles owner Norman Braman has reached an agreement to purchase the portion of the team owned by his brother-in-law and become the sole owner of the franchise, a team spokesman announced.

Braman will acquire the 35 percent interest of Edward Liebowitz for an undisclosed amount, a team spokesman said. The purchase must still be approved by the other NFL owners.

Braman, a Miami auto dealer, and Liebowitz purchased the Eagles from Leonard Tose last year for $65 million.
