Joey Dorsey picked up where he left last season and put up a show two minutes before the end of the friendly game in Italy between Sassari and Olympiacos. After getting a behind the back dish from Papanikolaou Dorey made a dunk which broke the backboard.
As you can see in the video, the backboard was pretty much destroyed, so the refs decided to finish the game earlier. For the record Olympiacos was leading 106-87.
