LeBron James undecided on jersey No. 6 or 23

CLEVELAND -- LeBron James has to make another big decision.

The NBA superstar turned to social media Friday to help him choose which number he'll wear next season with the Cavaliers. James wrote ''6 or 23....'' on his Twitter account and posted photos on Instagram of him wearing No. 6 and No. 23 wine and gold Cavs jerseys.

James wore No. 6 during his four seasons with Miami and also on the U.S. Olympic team. He used No. 23 in high school and during seven seasons in Cleveland.

James has had the top-selling jersey in the NBA six times during his career.

His return to Cleveland has given the city a boost, and the Cavs quickly sold out their seasons tickets in the hours after his announcement. James signed a two-year, $42.1 million contract last week.

The 29-year-old will be welcomed back to his hometown of Akron on Aug. 8, his family's foundation announced Friday. The ''Welcome Home LeBron Community Rally'' will be held at InfoCision Stadium on the University of Akron's campus. The rally, following James' annual ''Wheels for Education'' event, will be James' first public appearance since he chose to re-sign with the Cavaliers over the Heat.

James recently returned from Brazil, where he watched the World Cup final between Germany and Argentina. He's scheduled to take a Nike-sponsored trip to China in the next few weeks.
