Portland Trail Blazers guard Damian Lillard and San Antonio Spurs guard DeMar DeRozan have become the latest players to withdraw from playing for Team USA at this summer's World Cup in China, sources confirmed to ESPN on Tuesday.

They are the seventh and eighth players to pull out ahead of training camp, which starts Aug. 5 in Las Vegas. The national team is still waiting on answers from other players on the roster, including Kevin Love.

The Athletic was first to report Lillard's and DeRozan's withdrawals Tuesday.

The large amount of withdrawals is not unusual for World Cup years. In 2010, Team USA had 12 new players off the 2008 Olympic team. At the last World Cup, in 2014, it was 11 new faces off the 2012 Olympic team.

Several players are lined up to take the vacant spots, including Marcus Smart, Jaylen Brown, D'Angelo Russell and Julius Randle.
