Byline: Daily News Wire Services

Chris Webber encountered more problems with the law when he was fined $500 for having marijuana in his luggage while passing through an airport in San Juan, Puerto Rico.

Customs officials said the Sacramento Kings forward was briefly detained Friday night. He then continued traveling from the Dominican Republic to Barbados on a trip sponsored by the sporting-goods company Fila.

Webber is to play in a fund-raiser game Monday in Barbados. However, an official with the Barbados Amateur Basketball Association said Webber had not arrived by Saturday morning.

Webber, who had 11 grams of marijuana in his luggage, was traveling with Jerry Stackhouse of the Detroit Pistons and other athletes. Stackhouse arrived in Barbados on Friday night but could not be reached for comment.

The customs department said that because of the small amount of marijuana involved Webber was not cited for smuggling and would not be prosecuted for possession.

A customs dog on a routine inspection in the transit lounge at Luis Munoz Marin International Airport sniffed a carry-on bag that was tagged with Stackhouse's name, customs said. Stackhouse denied the bag was his, and Webber admitted it belonged to him.

DIVING: Coming off a disappointing performance in the spring nationals and a fourth-place finish last month in the Goodwill Games, the synchronized diving tandem of Tracy Bonner and Kathy Pesek decided to have some fun.

Both women dressed in metallic silver suits, but their performances were even more stunning as they won the women's 3-meter championship in the U.S. Diving Summer Nationals in Atlanta.

Chris Mantilla and Bryan Gillooly won the men's 3-meter synchronized title. David Pichler and Michelle Davison won the 3-meter individual championship.

COLLEGE: The presidents of eight Western Athletic Conference schools have formally voted to leave the league, nearly three months after they declared their intention to break away.

The Fresno Bee reported that the presidents voted Friday, a day after a proposed separation agreement was rejected by the remaining schools because the exiting schools would not give up $2.6 million in NCAA men's basketball tournament revenue, the newspaper reported.

The WAC was thrown into turmoil in late May when Air Force, Brigham Young, Colorado State, New Mexico, San Diego State, Nevada-Las Vegas, Utah and Wyoming declared their intention to leave the conference, effective July 31, 1999. Southern Methodist, San Jose State, Fresno State, Hawaii, Rice, Texas Christian, Texas-El Paso and Tulsa are the other conference members.

BOWLING: Pete Couture won the PBA's ABC Senior Masters in Akron, Ohio, beating Ron Garr 234-213 in the championship match.
