Either side (Winner or Loser) can input score to conclude this Matchup. In Team sports, only users with ‘Captain’ status within the group can input scores. Once scores are entered, the other party will receive a notification to accept or reject this score. Players / Team captains can reject initial score and input a NEW score to be sent to other party to accept. Scores are FINAL once its accepted.
This is a two-step verification process to allow fairer score-keeping for league players. Not everyone remember scores well, so submit the Matchup score earliest possible.
