Jason Terry's quiet fourth quarter was just about complete when Dallas center Brandan Wright waited near the basket for a lob pass from Shawn Marion. Wright's forceful slam on the alley-oop capped his season-high 23-point game, Dirk Nowitzki pitched in 22 and the Mavericks spoiled Terry's return to Dallas with a 104-94 victory against the Boston Celtics on Friday night.
