The Miami Heat, reeling from the continued injury absence of Dwyane Wade and an 0-7 record in the preseason, are on the verge of a double boost to their depleted roster, according to NBA front-office sources Wednesday.

Sources told ESPN.com that the Heat will soon complete a trade with the Minnesota Timberwolves to acquire swingman Ricky Davis and center Mark Blount.

The latest incarnation of the deal, according to one source, has Miami sending Antoine Walker, Michael Doleac and Wayne Simien to the Wolves for Davis and Blount.
