10:54pm: Gery Woelfel of the Racine Journal Times tweets that a Ridnour-Ekpe Udoh swap, which had been rumored around draft time, could once again materialize. I'd assume that would happen within the framework of this deal, though I'm not sure what that would accomplish for Minnesota, since Udoh's $4,469,548 salary is larger than Ridnour's.
7:41pm: The Wolves have reached an agreement with the Bucks to deal point guard Luke Ridnour to Milwaukee in an arrangement that will allow Minnesota the room it needs to finalize its pact with Corey Brewer, reports Jerry Zgoda of the Star Tribune. No salary will head from the Bucks to the Wolves in the trade, so presumably there will be draft picks and/or cash headed to Minnesota.
Marc Stein of ESPN.com reported earlier today that the teams were discussing the swap, as the Wolves sought to clear room to bring aboard Brewer along with the rest of their free agent haul. Ridnour, like J.J. Barea, was frequently mentioned in trade rumors over the past few weeks as Minnesota sought to clear its logjam at point guard.
Milwaukee's acquisition of Ridnour gives the team a backup for either incumbent point guard Brandon Jennings, or Jeff Teague, whom the Bucks have coveted. Ridnour is set to make $4.32MM in 2013/14, the final season of his contract.
