At age of 38, veteran San Antonio Spurs forward retired Thursday after 12 seasons and a reputation as one of the league's most menacing defenders, hounding opponents with a tenacity that some players groused was grimy than dogged.

He was not the most noticeable starter for a championship team early in his career. Drafted by Miami from Cal State Fullerton, he spent several seasons bouncing between clubs and earning little playing time.

But after his 2001 arrival in San Antonio, he found his place, eventually earning defensive player accolades and a regular starting job.

Bowen was named eight times to the NBA's all-defensive team. He finished runner-up three times in defensive player of the year voting. And though he never averaged more than 8.2 points a season, Bowen didn't shy from taking a clutch 3-pointer.

The team Boston Celtics decided to get to service of the free agent Marquis Daniel.

Daniels is almost six seasons; career high of 13.6 points and 4.6 rebounds in 54 games with the Indiana Pacers, 43 of them starts. The Celtics announced his signing on Tuesday.

The 28-year-old player spent three seasons with Dallas before moving to Indiana. For his career, he is averaging 9.4 points in 351 games, including 109 starts.

At 6-feet-6, Daniels gives the Celtics a big guard to come off the bench. They already have 6-foot-1 Eddie House, known for his 3-point shooting, to substitute for starters Ray Allen and Rajon Rondo.
