Mavericks forward Shawn Marion, who finished eighth in Defensive Player of the Year voting, went under the knife Friday and, for all you pre-Med MFFLs, shared the experience online via Mobli and then posted to his Twitter account (@matrix31).

He underwent a minor procedure to have a lipoma, a common benign fatty tissue, removed from the back of his shoulder. Marion didn't actually record the outpatient surgery, although he says he wishes he could have. He did provide a photo of the removed fatty tissue in a jar and a groggy, post-op Mobli.com video from the car on his way home explaining what just went down.

(Be warned, the mostly harmless video needs two bleeps for inappropriate language).

Marion arrived back in Dallas on Monday night, he tweeted, but don't expect Marion, who turned 34 on May 7, to sit still for long this offseason. His plans include his usual globetrotting as a man always on the move.

"I'm going to do it all, I enjoy my life, so I'm going do to what the hell I want to do," Marion said in his humorous showboat style during the team's exit interviews. "Its just that simple."

There's no telling yet if Marion will be a man on the move this summer from a professional standpoint, too. Marion has two years remaining on his contract. He could ultimately be included in a potential sign-and-trade deal as Dallas seeks to get younger, and he is one of two candidates along with Brendan Haywood that the Mavs can amnesty.

Or the Mavs can bring back their top perimeter defender and a core veteran leader.

"I can't sit here and tell you what they're going to do, what they decide not to do," Marion said. "It's up to those guys upstairs (Mark Cuban and Donnie Nelson) to make it happen."
