Former Celtics guard Marcus Smart had a nice reunion with his old teammates at TD Garden on Sunday night, and a not-so-nice reunion with one Boston fan.

A fan was ejected from TD Garden during the Boston Celtics ' 124-90 victory over the Washington Wizards on Sunday following a verbal exchange with Wizards guard Marcus Smart, who played for the Celtics for the first nine seasons of his NBA career.

Marcus Smart received a mostly warm welcome when he returned to Boston once as a visiting player on Sunday, but there was one tense incident between the former Defensive Player of the Year and a fan.
