MIAMI — Ray Allen will take less money for a chance at another NBA championship.

Allen told the Miami Heat on Friday night that he intends to accept their contract offer and leave Boston after five seasons, even though the Celtics could pay him about twice as much as the reigning NBA champions will be able to next season. Miami could only offer Allen the mini mid-level, worth about $3 million a year.

Heat owner Micky Arison tweeted the news just after 9:30 p.m. — or about 2:30 a.m. Saturday in Europe, where Arison has been for several days.

“I was just woken up with great news,” Arison wrote. “Welcome to the family.” Arison ended the tweet by making mention of Allen’s jersey No. 20, and did not mention the NBA’s leading 3-point shooter by name.

Allen, who will be 37 this month, arrived in Miami on Thursday for a visit, went to dinner with Riley, coach Erik Spoelstra, team executive Alonzo Mourning and others Thursday night, then left Friday to presumably decide his future.
