One of the biggest names left of the NBA free agent market, Leandro Barbosa, has official reached an agreement to a one-year-deal with the Boston Celtics according to Adrian Wojnarowski of Yahoo Sports via Twitter.

Barbosa played the majority of his season with the Toronto Raptors before being traded to the Indiana Pacers before the NBA trade deadline last season.

The 6-foot-3 Barbosa has averaged 12.5 points and 2.4 assists over 24.6 minutes per game in his career and averaged 8.9 points in 22 games last season with the Pacers. He'll join a backcourt that already includes Terry, Rajon Rondo, Courtney Lee, and Avery Bradley.

Celtics coach Doc Rivers already had suggested that Boston may have the deepest backcourt in the league when Bradley is healthy, and with Barbosa, who has speed and can handle the ball, Rivers isn't worried about having a pure backup behind Rondo.

"Every team doesn't have two great point guards," Rivers said. "Most teams don't. I think when you count Courtney Lee and (Terry) and Avery, all three are ball handlers -- none of the three are pure point guards. But they can certainly play the other."

Earlier during the off season it was rumored that there was a mutual interest between Barbosa and the Los Angeles Lakers, especially after the Lakers acquired veteran point guard Steve Nash who had been recruiting for his former teammate to sign with the Lakers.
