The two former MVPs could participate in their first workout session as early as Wednesday, sources say. Rose inked his one-year deal with the Cleveland Cavaliers on Tuesday.
James has spent the past few days vacationing and working out in Las Vegas.
James sold Rose on the idea of coming to Cleveland for a new beginning and a chance to compete for an NBA title. This week's workout should help expedite the on-court chemistry that tends to occur with new teammates during training camp in late September.
