Boston Celtics president of basketball operations shot down the latest Ray Allen trade rumor Friday, telling the Boston Globe there was “no truth” to a Yahoo! Sports report that the team was working on a deal to send Allen, Brian Scalabrine and J.R. Giddens to the Washington Wizards in exchange for power forward Antawn Jamison and small forward Caron Butler.

Although one source warned ESPN.com it would be a mistake "to sleep on that one," another source close to the situation insisted that a Boston-Washington swap looks "very doubtful" because of the considerable long-term expense Boston would be taking on -- for players who play the same positions as Paul Pierce and Kevin Garnett -- and because of Washington's reluctance to part with Jamison.

Butler and Jamison are both under contract for next season at a combined $24 million Jamison is also on the books for $15 million in 2011-12. Allen’s $19.7 million contract expires at the end of the season.

The Celtics weren’t the only team rumored to have interest in a deal with the Wizards, who could be looking to unload big contracts and undergo a rebuilding process. The latest rumblings indicate the Dallas Mavericks and Wizards are talking about a deal that would include Butler.

Allen’s name has come up in several rumored deals over the last week or so, including ones that would have netted the Celtics Kevin Martin from the Sacramento Kings, or Mota Ellis from the Golden State Warriors.

"I have no control over trade rumors people," Allen announced to his fans via his Twitter account Friday. "Let's just focus on being positive. I am a Celtic. Green all day."

Earlier this week, Ainge told Boston sports radio station WEEI that he was not looking to "blow it up", preferring to make a minor move.

"I'll know more by this time next week, if there's anything we can do to win better this year and still not hurt us down the road," Ainge said. "So I'm exploring, those are the only kind of deals I'd consider doing right now. Right now, I'm not ready to blow it up. [Maybe] if there was a very intriguing young player, but those are not available."
