Mike Hogan, the Philadelphia Eagles' starting fullback, was engaged in an offseason workout at Veterans Stadium yesterday - got to keep onward and upward in the NFC East, you know - when the long arm of the law intervened. Drug bust!

Hogan; second-string Eagle running back James Betterson; former Eagles Thomas Campbell and Will Wynn (briefly a Redskin defensive line reserve in 1977), and four other men were arrested in a narcotics dragnet involving police from Philadelphia and several New Jersey suburbs.

Camden County Prosecutor John B. Mariano said the eight were accused of various violations involving cocaine. Campbell was held in $15,000 bail, the others $10,000 each. Mariano said the arrests resulted from two months' investigation including electronic surveillance; and that all were charged principally with conspiracy to deal cocaine on diverse days between May 22 and June 20. Bail was posted last night . . .

Bob Lemon, hardly settled into his easy chair upstairs with the Yankees, evidently has only to say "yes" to return to an American League East dugout as manager. Not New York's but Cleveland's.

"It comes out of left field," Lemon, 58, commented of the bid from Indian President Gabe Paul to come home to the club for whom he pitched 207 victories (1946-58) and replace Jeff Torborg. "I'm not in the frame of mind to make a decision. "I'll have to talk with the boss (George Steinbrenner) here and the boss (Paul) there." Meanwhile, Torborg stays.

The wolves were at the door in Kansas City yesterday, in the persons of the owners of the Minnesota North Stars seeking to buy Minneapolis back into probasketball, when city officials reached an agreement to keep the Kings - well, at least for 1979-80.

The club elected to stay, and play in K.C.'s Municipal Auditorium, in view of "commitments and assurances" to help make up for the switch to the 9,300-seat auditorium from 16,694-capacity Kemper Arena. Kemper is out of commission because of damage from a June 4 storm that sent its roof crashing to the floor.

Out of the NBA: referees Bernie Fryer, Bill Jones, Ken Falkner and one-year colleagues Roger McCann, Tommie Wood, Jess Thompson, Dick Schaper, Blaine Reichelt, Bob McAlister and Terry Durham, who were brought in when the league went to three-man crews for 1978-79. The owners' recent decision to revert to the two-ref system sends them packing - under NBA's agreement with the refs' association to drop the bottom 10 whistle-tooters based on a rating system.

"We have now dropped from 38 officials to 27," noted Norm Drucker, league supervisor of same. The 11th dropout? Flamboyant Richie Powers, retiring at 48, after 22 years' service and saying, despite last season's Battle of the Zones, "I am leaving under the best of terms. I hope to stay with the league in some capacity". . .

Charles Town is agog over the testimonial dinner coming up Sunday (Cliffside Motor Inn, 7 p.m.) for the wonderful old jockey, Sam Palumbo. Ride 'em!
