James announced in July that he was returning to Cleveland after spending the last four seasons with the Miami Heat.
The forward was drafted No. 1 by the Cavaliers in 2003 and played his first seven seasons with them.
After he announced his return, James asked fans what jersey number he should wear, the No. 23 he wore during his first stint in Cleveland or the No. 6 he wore with the Heat, before deciding on No. 23.
The Cavaliers open the season Oct. 30 against the New York Knicks.
