I’ve seen it happen in the NBA before, but if a player fouls out with no one else able to play, then he gets a technical foul for it but stays on the court. And any additional foul called against him gets an additional technical foul called lol.I've never seen that. I actually thought you had to forfeit if you couldn't put 5 guys on the court.
It’s what this famous picture is from:
I had no idea what they did for college or that you could play 3vs5.
