DALLAS -- Dirk Nowitzki, now three points away from becoming No. 20 on the NBA's all-time scoring list, recorded the 1,000th block of his career early in the first quarter of Monday's game.
Nowitzki swatted away Boston guard Avery Johnson's reverse layup attempt.
He has four points so far against the Celtics. He needs seven to pass former Celtics great Robert Parish.
