BASEBALL

WASHINGTON (AP) Former Yankees second baseman Chuck Knoblauch agreed to talk to a House committee investigating drug use in baseball, and the session was postponed until later this week.

The committee issued a subpoena for Knoblauch last week after he failed to respond to an invitation to testify. Knoblauch originally was to give a deposition Jan. 24, a session that was postponed until Tuesday. Under the new schedule, Knoblauch will give a deposition or transcribed interview Friday.

The appearance is in preparation for a Feb. 13 hearing, which is to include Knoblauch, Roger Clemens and Andy Pettitte. Also scheduled to testify are Brian McNamee, the former personal trainer for Clemens and Pettitte, and former Mets clubhouse attendant Kirk Radomski.

WASHINGTON (AP) Nationals catcher Paul Lo Duca had arthroscopic surgery on his left knee and is expected to be sidelined four to six weeks.

The operation was to repair a torn medial meniscus, and Lo Duca will begin a rehabilitation program later this week.

BEIJING (AP) Six workers have died building venues for the 2008 Beijing Olympics over the last five years, an acknowledgment that came after a series of clarifications by a Chinese official.

Ding Zhenkuan, deputy chief of Beijing's Municipal Bureau of Work Safety, initially told reporters no deaths had taken place at the 91,000-seat National Stadium, known as the "Bird's Nest" and the site for the opening and closing ceremonies.

He later said two died there and then added there were six worker deaths in total at all sites, without elaborating on the other four deaths.

It is not unusual in China for communist government officials to make seemingly inaccurate or contradictory statements. Li Yizhong, minister of the State Administration of Work Safety, said last week he was unaware of work-related deaths on the project but promised to investigate.

ANAHEIM, Calif. (AP) Teemu Selanne returned to the Stanley Cup champion Anaheim Ducks after missing the first half of the season while contemplating retirement.

The unrestricted free agent signed a one-year deal and then practiced with the team before it departs Tuesday for an eight-game, 15-day road trip.

Selanne followed Stanley Cup MVP Scott Niedermayer in returning to the team. Niedermayer came back in December after pondering retirement, and he scored a goal in Sunday's All-Star game in Atlanta.

Selanne, a 37-year-old right wing, had 48 goals and 46 assists last season, when he ranked third in the NHL in goals, led the league in power-play goals with 25 and tied for first in game-winning goals with 10.

DERBY, England (AP) A Detroit consortium became the new owners of Derby County, the fourth Premier League soccer team to fall into American hands.

General Sports and Entertainment takes control of a club that is last in the 20-team division and facing almost certain relegation to the League Championship next season.

Derby is the latest top division English club to be owned by Americans, joining Manchester United, Liverpool and Aston Villa. Also, New York Yankees owner Hank Steinbrenner told The Associated Press he is interested in buying into English soccer.
