STEPHON’S HOOP SKIRT TO TESTIFY

The former Knick intern whose sordid sex encounter with hoops star Stephon Marbury was laid bare in federal court this week has agreed to take one for the team.

Lawyers representing Madison Square Garden plan to call Kathleen Decker, 24, to give her version of a conversation with former Knick executive Anucha Browne Sanders about the co-ed’s racy romp in the star point guard’s truck, sources said.

Marbury admitted in Manhattan federal court on Wednesday that he scored with the intern in April 2005 after brashly asking her, “Are you going to get in the truck?”

“Yes” was the answer, according to the married Knick, who admitted to having subsequent steamy meetings with the intern.

Decker, who was also romantically linked to Marbury’s cousin, waited until November 2005 to tell supervisors about her fling with the point guard, and he was never questioned.

In the meantime, Decker graduated from St. John’s University and landed a job in the communications department for the Garden of Dreams Foundation.

Described by co-workers as “pretty” and a “great girl,” the perky publicist appeared on the CBS show “Power of 10” last month – blowing a possible $10 million win by underestimating how many married Americans stay in love.

Garden lawyers have hinted that Decker could finger Sanders for allegedly forcing her to lodge the internal complaint.

Sanders is suing Knick coach Isiah Thomas and the Garden for sexual harassment in a $10 million case now under way.

Contacted by phone, Decker’s mother told a reporter, “I have nothing to say to you.”

The Garden refused to say whether it has a policy related to players socializing with interns.

But a former intern who worked with Decker told The Post it was a “major no-no.”

“They definitely encouraged us not to. I think anyone who wanted to keep a position there abided by those rules,” said Mia Welsh, 29.

Decker is also on Sanders’ witness list, but it’s not clear whether her lawyers will also call her.

An ex-MSG staffer recalled that rumors had swirled about Marbury and an intern – and wasn’t surprised to hear it turned out to be Decker.

“Guys were very, very after her, and why not? She is very pretty,” the former employee said. “Everyone was after her . . . because she was cute.”

A self-described “roller-skate limbo champion,” Decker made two appearances on “Power of 10.”

She was eliminated after she missed the answer to the question, “What percentage of married Americans said they do not currently love their spouse at least as much as they did on their wedding day?”

Decker locked in a range of 15 to 55 percent, but the answer was 9 percent.
