Colaluca to RBNY?

Yesterday the Rapids official blog reported that Nico Colaluca was on the the Rapids preseason roster. Today Soccer by Ives reported that Colaluca was spotted practicing with the New York Red Bulls. Presumably, if Ives correctly identified Nico, a trade is about to be announced as its not standard procedure to allow one team's player to practice with another team before the new team actually has his rights.
