Thomas Hearns' sore right pinkie and ring finger seem set to put off the Hearns-Marvin Hagler sockfest in Windsor, Ontario. Shades of Gerry Cooney's sore shoulder and the Cooney-Larry Holmes delay.

It's "99 percent certain" the May 24 middleweight title fight will be postponed, UPI quotes "a source close to" Emanuel Steward, Hearns' manager-trainer.

He resumed sparring, but the little finger apparently became infected and, Steward said yesterday, "remained swollen . . .

If the Raiders win, he continued, there would be an immediate separate, short trial to determine damages . . .

Williamsburg's Skeeter Heath shot 63 in "rabbit" qualifying for the Houston Open, including a run of 10 birdies in 12 holes and a start of which he commented, "I still can't believe I shot 28 for nine holes. It sounds more like a belt size" . . .

Green Bay Packers, electing Judge Robert G. Parins the NFL franchise's first full-time chief executive, reported operating loss for '81 of $987,179--but, thanks to investments, net income of $871,230 . . . In baseball, his team trails the field in attendance, but Dan Galbreath, club prez, avers: "The franchise will not be moved after the 1982 season and the club is not for sale.
