Boston, MA -- (Sports Network) - Forward Rasheed Wallace has reportedly agreed to sign with the Boston Celtics.

Reports from FOXSports.com and the Boston Globe on Sunday indicated Wallace is expected to sign a two-year contract for the mid-level exception. He cannot formally do so until Wednesday, the first day NBA free agents can sign.

Wallace, 34, spent the last five-plus seasons with Detroit, helping the Pistons win an NBA title in 2004. He averaged 12 points and 7.4 rebounds in 66 games (63 starts) for Detroit last season.

The four-time All-Star broke into the league in the 1995-96 season with Washington, after the then-Bullets selected him fourth overall in the '95 draft. In 1,009 career games over 14 seasons with Washington, Portland, Atlanta and Detroit, Wallace has averaged 15.0 points and 6.9 boards.
