As time passes it is becoming less likely that the Dallas Mavericks are going to pull off a trade for New Jersey point guard Jason Kidd, according to Marc Stein of ESPN.com.

A source close to the negotiations said, "I'd have to say it's going away."

A league source told ESPN.com that the two teams continued to exchange trade ideas on Friday, but the latest obstacle is the new development surrounding the infamous "side deal" involving Jerry Stackhouse.

The league does not permit trades to be completed during All-Star weekend.
