Should a player play from the start and get injured after the whistle, the pairing remains valid. If he is injured before kick-off and cannot play (not in the starting line-up), the pairing concerned will be cancelled and your potential winnings minimised. If you fall below the minimum number of three pairings, the entire Pair Up participation will be cancelled and your participation fee will be refunded.
