In the wake of multiple withdrawals of frontcourt candidates for the national team, USA Basketball has invited Atlanta Hawks forward Paul Millsap to its training camp this week in Las Vegas, sources told ESPN.

After initially planning to make no roster additions after the withdrawals of Kevin Love, Blake Griffin and LaMarcus Aldridge, USAB officials decided to bring Millsap in as a potential floor-spacer with the ability to play small forward or power forward internationally.

Millsap's addition takes the number of senior players in camp under Team USA coach Mike Krzyzewski to 19.

After a successful first season with the Hawks, Millsap will join the likes of DeMarcus Cousins, Andre Drummond and Kenneth Faried in trying to capitalize on the high-profile absentees to claim a spot on the final 12-man roster that will represent the United States at the inaugural FIBA Basketball World Cup in Spain starting Aug. 30.

USA Basketball announced Love's withdrawal Saturday, citing "his current status" in a reference to the trade limbo Love is in at the moment with the Minnesota Timberwolves.

Love, Griffin and Aldridge were all scheduled to join Kevin Durant in a high-powered Team USA frontcourt, but Griffin and Aldridge opted for additional offseason rest heading into training camp in October as opposed to playing for the national team.
