Noah, who was shooting free throws as the media entered the Verizon Center floor, took exception to the fact that Miles told him to leave the court as the rest of his teammates were finishing up their workout.
The pair exchanged expletives as Noah continued shooting. A few moments later Noah walked toward the locker room to fulfill his pregame interview responsibilities.
Bulls coach Tom Thibodeau brushed off the incident before Friday's game, saying it was "much to do about nothing."
This isn't the first run-in Miles has had with Chicago personnel. He had another verbal altercation with a Chicago-based reporter before the Bulls' shootaround ended on Jan. 17.
The Wizards come into Friday night's Game 3 leading the Bulls 2-0 in their first-round Eastern Conference playoff series.
