Heat second-round pick Pat Beverley saw his Olympiakos team fall to FC Barcelona in the Euroleague title game on Sunday.
Beverly played 10 scoreless minutes for Olympiakos.
Miami's other second-round pick last season, forward Robert Dozier, has also completed a season in Greece.
Dozier averaged nine points in 28 appearances for VAP Kolossos.
Beverley and Dozier are expected to participate with the Heat's summer-league team in Las Vegas in July, according to the South Florida Sun-Sentinel.
