Player A throws disc to Player B right at the end zone line. Player B looks around and calls himself in. Opposing player calls player B out and begins counting stalls. Player B tries to explain that he thinks he's in, opposing player continues counting stalls. Player B throws an incomplete pass. Discussion then occurs and opposing player explains Player B must say "contest" in order to stop the play because opposing player believes player B will throw it once an open person is there.
I know by throwing the disc away, it's a turnover already. But my question is if the opposing player should have continued counting stalls. Should play have stopped once the disagreement occurred or does player B need to "contest" their out call? And should player B even be the one to "contest" and not the opposing player "contesting" player B's in call? My understanding is if there is a disagreement on a call, play automatically stops and discussion occurs then followed by a check.
Sorry for the long post on probably a very minor issue but I wouldn't definitely appreciate some clearing up here! Thanks!
Is the word "contest" needed to stop play?
