Sources told ESPN.com the Grizzlies will acquire forward Ed Davis and veteran guard Jose Calderon from the Raptors and then move Calderon to a third team to ultimately make this a three-team deal.

The Detroit Pistons, sources said, are one of the prime options to take on Calderon, having pursued the Spanish floor leader all season.

Sources told ESPN.com that the Pistons have agreed to send Tayshaun Prince and Austin Daye to the Grizzlies to acquire Calderon as part of the trade.

Memphis, sources said, is also expected to receive a second-round pick from Toronto as part of the deal.

The Raptors, sources said, are expected to take on Grizzlies reserve center Hamed Haddadi in addition to Gay.

The Dallas Mavericks, sources say, were also interested in acquiring Calderon but were not prepared to surrender swingman Vince Carter, whom Memphis coveted to help fill the void created by Gay's departure.
