The NBA's trade deadline is a month away, but the most anticipated deal of the trading season could be completed by the end of the weekend, according to league sources.

And if it goes through, Rasheed Wallace's checks will soon be cut by the Dallas Mavericks.

"I'd put the chances at 50-50 right now," said one source close to the negotiations. "We hope to find out tonight or tomorrow."

At the very least, sources say, Dallas and Portland are motivated to bring some sort of finality to their ongoing discussions instead of letting speculation continue to smother their players from now until the Feb. 19 trading buzzer. That resolution would come in the form of a trade that sends Antawn Jamison and Tariq Abdul-Wahad to Portland for Wallace or a decision by one or both parties to end the talks and attempt to move on with their seasons.
