BRIEFLY : MIDWEEK FOR ELWAY.

Byline: Daily News Wire Services

John Elway's announcement that he is leaving football is expected to be made the middle of this week, a Denver Broncos spokesman said Sunday.

Unofficially, the star quarterback all but announced his retirement Saturday in an interview with Denver TV station KCNC in Pebble Beach, where he was playing in a golf tournament.

Elway reportedly considered announcing his decision two weeks ago, but owner Pat Bowlen was in Australia promoting the Broncos' preseason game there. Then last week, the announcement was put off because of the high school shootings in suburban Denver.

Out of respect for the victims, some of whose funerals were scheduled for today, the Broncos further delayed an Elway announcement.

``We're (looking at) a midweek press conference, most likely Wednesday,'' Broncos spokesman Jim Saccomano said.

Two years ago quarterback Chris Miller thought he might never play football again, but a newspaper reported Sunday that he could be back next season - with the Broncos.

Four years after retiring from football, Miller has agreed in principle to sign with the Broncos, the Denver Rocky Mountain News reported.

Veteran quarterback Warren Moon has agreed to a two-year deal with Kansas City, said Chiefs general manager Carl Peterson.

OLYMPICS: Lord Killanin, president of the International Olympic Committee during one of its most turbulent periods, died Sunday. He was 84.

Killanin, who had been ill for some time, died at his home in Dublin, Ireland, his family said. The cause of death was not announced.

He became president of the IOC in 1972, taking over from American Avery Brundage just after the massacre of Israeli athletes and coaches at the Munich Olympics. He left in 1980.
