When a team uses all their 12 players, and there is a scenario that required an additional player on court, their is an appearance but at the box-score - players are being placed one above the other.
Here is the game that I've seen it
http://www.buzzerbeater.com/match/42322073/reportMatch.as... - A scrimmage game that the opposing team did not showed up, and somehow I've got one foul after the other (although it has no meaning, as I got a technical win of course), which caused my players to be fouled out rapidly.
