USA Basketball now has a full 12-man roster for the Tokyo Games, after Chicago's Zach LaVine and Detroit's Jerami Grant accepted invitations Wednesday to join the team that will try to win the program's fourth consecutive Olympic gold medal.

LaVine's decision was confirmed by his agent, Nima Namakian. Grant's decision was confirmed by a person familiar with the situation, who spoke to The Associated Press on condition of anonymity because USA Basketball has yet to formally reveal the full roster.

The Olympic bid continues an incredible year of transformation for Grant, a second-round pick in the 2014 NBA Draft. The 27-year old was a role player with the Denver Nuggets last season before signing a three-year, $60 million contract with the Detroit Pistons last November. He became the Pistons' top player this season, and now he's a potential Olympic gold medalist.

The challenge for the Americans will be keeping the group together. There has already been one change; Brooklyn's James Harden, who had briefly committed, has since told the national team that a hamstring injury that affected him during the NBA playoffs would not allow him to participate, the person familiar with the roster decisions told AP.

So, for now, the Olympic team that will be coached by Gregg Popovich in Tokyo: Washington's Bradley Beal, Brooklyn's Kevin Durant, Miami's Bam Adebayo, Milwaukee teammates Jrue Holiday and Khris Middleton, Portland's Damian Lillard, Cleveland's Kevin Love, Phoenix's Devin Booker, Golden State's Draymond Green, Boston's Jayson Tatum, LaVine and Grant.

The team has a combined 37 All-Star selections, led by Durant's 11. The team will not be officially complete until USA Basketball sends its roster to FIBA, something that won't happen until next month.

Durant is a two-time Olympic gold medalist, after being part of the 2012 and 2016 teams. Green also helped the U.S. win gold in 2016, Love in 2012.

Holiday, Middleton and Booker are still in the NBA playoffs. Game 7 of the NBA Finals may happen as late as July 22 — just three days before the Americans open Olympic play in Tokyo against fellow medal favorite France, the nation that knocked the U.S. out of medal contention at the Basketball World Cup in China two years ago.

USA Basketball managing director Jerry Colangelo has said that contingencies are being made in case any players miss camp and have to arrive in Tokyo after the rest of the Olympic team because of their NBA playoff schedules.

Grant — who averaged 22.3 points for Detroit this season — played for the 2012 U.S. team that went 5-0 on its way to the gold medal at the FIBA Americas U-18 Championship in Brazil.
