Martina Hingis is returning to professional tennis -- again.

The former top-ranked player, who retired from the WTA Tour three years ago because of an ankle injury, won five Grand Slam singles titles in her career and was the youngest player to be ranked No. 1.

The 25-year-old Swiss player made a brief comeback in February, losing in the first round of the Volvo Women's Open in Thailand. Her previous match was in October 2002, but she believed she prematurely returned to competition following left ankle surgery, and withdrew from all remaining tournaments.

"I was never happy that my injuries cut my career short and ultimately forced my decision to step away from tennis," Hingis said. "I have enjoyed my time away from the court. However, I miss the game and the challenge of competing at the highest level of tennis and I want to gauge whether I can stay healthy and compete against today's top players."

* SOCCER: FC Utrecht defender David di Tommaso died in his sleep at age 26. The cause of death wasn't immediately known, the Dutch soccer club said.

"He ate dinner last night and went to bed as he usually did. He didn't complain of feeling ill," club doctor Frank van Hellemondt said.

The French-born Di Tommaso was voted the team's player of the year last season by fans. Di Tommaso, who had one goal this season, played in Sunday's 1-0 victory over Ajax. . . .

Barcelona beat a combined Israeli-Palestinian team 2-1 in a "Match for Peace" aimed at supporting efforts at halting the conflict between the two. Deco scored on a lob in the 60th minute at Camp Nou in Barcelona, and Maxi Lopez made it 2-0 five minutes later.

Abas Suan scored in the 67th minute for the visitors, who were coached by Israeli Dror Kashtan and Palestinian Jamal Hadadi. . . .

FIFA and the World Anti-Doping Agency have taken their dispute over minimum doping bans to sport's highest tribunal.

The Switzerland-based Court of Arbitration for Sport said it received requests from both sides to provide an advisory opinion on the unwillingness by FIFA, the sport's world governing body, to adopt WADA's recommended two-year ban for first-time drug offenses.

* COLLEGES: Ohio football coach Frank Solich will be put on probation by the university following his drunken driving conviction. Solich also will publicly address his arrest and conviction and become involved in alcohol education initiatives on campus.

Solich, 61, appeared to be passed out when police found him Saturday night in his car, which was facing the wrong direction on a one-way street and in drive, according to a police report. He was found guilty Monday after pleading no contest. He had his license suspended for 180 days, was fined $250 and ordered to complete a three-day driver intervention program.

* HIGH SCHOOLS: Andy Muir, who led W.T. Woodson's field hockey team to a Virginia AAA championship in 2003, has resigned to spend more time with his family. Muir's resignation, first reported by the Connection Newspapers, came after a season in which the Cavaliers went 20-3-1 and reached the state semifinals. He will remain in his position at Woodson as assistant director of student activities.

* OBITUARIES: Vic Power, a seven-time Gold Glove-winning first baseman and one of the first Hispanic players in the major leagues, has died at 78. He had cancer.

Power achieved a rare feat in 1958, stealing home twice in a game when he played for the Cleveland Indians. He had only three steals all season. Power came up to the majors with the Philadelphia Athletics in 1954 and played for 12 years. He had a career batting average of .284 and hit 126 home runs. . . .

Jack Concannon, the former Boston College star who started at quarterback for the Chicago Bears in the late 1960s and early '70s, died of a heart attack. He was 62.

Concannon played for the Eagles (1964-66), Bears (1967-71), Packers (1974) and Lions (1975). He passed for 6,270 yards and 36 touchdowns with 63 interceptions in 90 career regular season games.

Concannon was also a member of the Screen Actors Guild, appearing in the movie "M*A*S*H" as well as "Brian's Song."
