The Celtics just got even older.

Guard Michael Finley, who turns 37 Saturday, will sign with them for the prorated veteran's minimum after having his contract bought out Monday by San Antonio. His agent, Henry Thomas, said in a phone interview Thursday afternoon his client is "excited'' about joining Boston.

"It's an opportunity for him to be in the rotation,'' Thomas said. "I think he'll get minutes. (The Celtics) have a need for a perimeter player who has his savvy. He's a veteran, and he still has the ability.''

Finley barely played this season for the Spurs. He asked for and was given a buyout in hopes of signing with a contender for the stretch run.

"It was really the first time in his 15-year career he was in that position,'' Thomas said of Finley getting into just 25 games while averaging 3.7 points for the Spurs. "But he understood the situation. ... Boston was at the top of the list. It's somewhere he can seriously contend for a ring.''

Other contenders, such as the Lakers and Denver, called. But the Celtics were said by Thomas to have shown by far the most interest.

Thomas didn't rule out Finley looking to play at least one more NBA season. He said Finley will evaluate how he feels after the season.

Finley, a two-time All-Star who has a career scoring average of 15.9 and won a title with the Spurs in 2007, will be the oldest player on Boston's roster, but it won't be by a lot. The Celtics have Rasheed Wallace, 35, Ray Allen, 34, and Kevin Garnett, 33.

I think Boston really preparing for the play offs. The acquisition of Robinson and Finley will give veteran presence in their second unit. I just hope it wont disrupt the chemistry of the team. It seem like Danny Ainge is already desperate and disappointed in the recent set backs of the team that's why he infused some talent in a talent laden team already. I know Finley will give them some perimeter offense but his defense might be his liability due to his age.
