A source familiar with the negotiations has confirmed to WEEI.com that former Celtics  forward Leon Powe  is in Cleveland and will sign a two-year deal with the Cavaliers  upon the completion of the second part of his physical on Wednesday.
After establishing himself as a reliable contributor on the Celtics bench, Powe’s future was in question following a string of knee injuries last season. After missing 13 games with a right knee injury, Powe tore the ACL in his left knee during Game 2 of the first round of the playoffs against the Chicago Bulls . He missed the remainder of the postseason.
This summer the Celtics chose not to exercise their option on Powe’s contract, making the injured 25-year-old an unrestricted free agent in a tumultuous economy. According to the source, Powe is expected to return in February. (The Cavaliers will make their first trip to Boston on February 25 for a nationally televised game on TNT.) While he may not have an impact for the first half of the season, a championship contending team like the Cavaliers could benefit from his playoff experience down the stretch.
Powe was drafted by the Denver Nuggets  with the 49th pick in the 2006 NBA Draft. The Celtics acquired his draft rights in exchange for a future second round pick. He averaged 6.6 points and 4.3 rebounds during his three-year career in Boston, while posting 5.0 points and 2.8 boards in 25 playoff games.
Powe is the founder of Fresh Start Family Services , a non-profit organization in the Bay Area which provides support and education for children who, like himself, are growing up in the foster care system. He will participate in a series of basketball camps and community events  this weekend in California.
