The Associated Press reports: Phoenix Suns guard Stephon Marbury will serve 10 days in jail after pleading no contest Friday to drunken driving.

Marbury, acquired a year ago by the Suns in the trade that sent Jason Kidd to New Jersey, was stopped Feb. 8 while driving his Bentley convertible 25 miles above the speed limit on a busy street.

He registered a 0.18 blood alcohol level, more than twice Arizona's legal limit. A level about 0.15 is considered extreme driving under the influence.

Marbury, who entered the plea in Scottsdale Municipal Court, also agreed to pay a $1,000 fine and attend alcohol education classes. He was scheduled to start serving the sentence Saturday, according to court records.

''Rather than extend this process and try to avoid my obligations, I fully intend to serve the required penalty levied by the court,'' Marbury said in a statement.

The NBA suspended Marbury on Friday for one game as a result of the plea. He will sit out Phoenix's season opener at Seattle on Oct. 30.

Marbury also will match the fine his suspension carries with a contribution to alcohol abuse and awareness programs, the Suns said.

''Most important to me, however, is that the message be heard loud and clear that I was wrong to do what I did,'' Marbury's statement read. ''I am fortunate no one was hurt by my actions. I pledge I will do what I can through personal and financial outreach to heighten the awareness of the dangers of drinking and driving.''

Suns president Bryan Colangelo said that while he was disappointed in Marbury's actions, ''I do believe he has learned a great deal from this experience and that he is regretful for his actions.''

ESPN?s David Aldridge reports that Shawn Marion will remain with the Suns for quite a while. On the first day of rookie contract extension signings, the Suns signed Marion to a maximum 6-year deal. The total value of the extension will probably be in excess of $80 million.  

The deal makes Marion a key part of the Suns' rebuilding plan, which includes first-round picks Amare Stoudemire and Casey Jacobsen.

Marion, the ninth overall pick in the 1999 draft, averaged a career-high 19.1 points per game for Phoenix last season. The 6-foot-7, 215-pounde UNLV alum also led the Suns in rebounding (9.9), steals (1.83), field-goal percentage (.469) and free-throw percentage (.845).

Marion will represent the United States at the World Championships, which begin August 29 in Indianapolis. The 24-year-old also played for Team USA at the 2001 Goodwill Games in Australia, starting all five games and averaging 13.4 points and 7.6 rebounds for the gold medal winners.
