WASHINGTON, Aug. 13 (Xinhua) -- Kyle Lowry of the NBA champion Toronto Raptors will withdraw from the United States' national team's scrimmage Friday as his surgically repaired thumb has not recovered sufficiently enough to allow him to fight for the FIBA World Cup.

Lowry, who underwent an operation on his left thumb last month, is expected to be on court for training Tuesday through Thursday in Los Angeles.

Lowry's decision means that there will be only 15 players in the running for 12 spots on the final roster.

The remaining national team players include Miami's Bam Adebayo, Sacramento's Harrison Barnes, Kyle Kuzma of the Los Angeles Lakers, Boston's Jaylen Brown, Jayson Tatum and Kemba Walker; Milwaukee's Brook Lopez and Khris Middleton, Utah's Donovan Mitchell, Denver's Mason Plumlee, Houston's P.J. Tucker, Indiana's Myles Turner and Chicago's Thaddeus Young.

Several top players have backed out of playing for the US World Cup squad, with personal matters, adjustment times needed for new teams or lost rest time as reasons.
