Monte Morris and OG Anunoby are two of 13 NBA players named to Nigeria's preliminary roster for the upcoming Olympics.

Nigeria, led by Mike Brown, begin training camp on June 20.

Eight current or former NBA players are set to make their debut for Nigeria, including Jahlil Okafor, Udoka Azubuike, KZ Okpala and Precious Achiuwa.

"I could go on and on in naming the contributions that each guy is bringing to the table for their teams, which is exciting for me, and it should be exciting for all of Nigeria, with the impact that they're having in the NBA, because they are the future of the program," said Brown.
