DALLAS — Aaron Gordon is available in Dallas to make his return from a calf strain that sidelined him for nine games, the Nuggets announced Sunday. Gordon will be on a minutes restriction against the Mavericks, a league source told The Denver Post. Denver’s starting power forward has missed 20 games this season with the same injury, which has caused two separate prolonged absences. Gordon, 29, is averaging 13.7 points, 5.8 rebounds and 3.1 assists per game when he plays.
