Carlos Arroyo has told the South Florida Sun-Sentinel that he will fly back from his native Puerto Rico on Thursday to sign a deal with the Heat.
Arroyo started Miami's final 21 regular-season games and all five playoff contests at point guard.
"Looking forward to a championship!!!" Arroyo wrote in an email to the Sun-Sentinel. "Excited!!!!"
He will join Mario Chalmers as Miami's second point and become the team's 13th player under contract.
