BOSTON – The cities of Boston and Philadelphia are about to watch a very rare event take place this weekend. The Celtics and 76ers will play each other on consecutive nights in separate cities.

The fun will tip off at 7 p.m. Friday night in Philadelphia when the Celtics head to the Wells Fargo Center. When that game is completed, the teams will head to separate airplanes and fly to the same destination, Boston, for their 7:30 p.m. tilt Saturday night in TD Garden.
