The on-again, off-again deal with the Boston Celtics acquiring Kevin Garnett apparently is back on.

According to sources, the current deal on the table has the 6-foot-11 Garnett heading to Boston and the Celtics dealing away Al Jefferson, Theo Ratliff's hefty expiring contract and Rajon Rondo. There may also be other players and draft picks involved.

It's not quite done, but three industry sources ? including one close to the Celtics ? told FOXSports.com that it's extremely close and could become official within the next 48 hours.

"It's basically done," one source said. "If it does happen, this will make the Celtics relevant again."

Celtics boss Danny Ainge attempted to trade for the Minnesota Timberwolves star forward prior to the NBA Draft, but the 31-year-old perennial All-Star had no interest in heading to Boston.

However, things may have changed now that Ainge and the Celtics pulled off the draft day deal with Seattle for Ray Allen.

According to RealGM.com, the trade will not work with just the pieces mentioned in the Fox Sports article.  Boston will need to add more to accommodate any deal that includes Garnett.
