MILEPOSTS—FREED: Former Miami Dolphin running back EUGENE (Mercury) MORRIS, 38, after serving three years in a Miami prison for cocaine trafficking.

Rather than go to trial, however, Morris agreed to a plea-bargaining arrangement in which he did not contest a lesser cocaine-conspiracy charge. Circuit Judge Ellen Morphonios then allowed Morris to apply his three years already served against the new 4½-year sentence and awarded him 1½ years for good behavior, thereby eliminating his new sentence altogether.

HIRED: As coach of the Detroit Red Wings, JACQUES DEMERS, 41. Demers, who has coached the St. Louis Blues for the past three seasons, acknowledged that a higher salary offer convinced him to leave a playoff team to coach the Red Wings, who were 17-57-6 last year.

ORDERED: By the 9th Circuit Court of Appeals in San Francisco, a new trial to determine damages to the Los Angeles Raiders resulting from the NFL's attempt to prevent the team from moving from Oakland to Los Angeles.
