Leeds' Jordan Stevens has been banned from all football-related activity for six weeks for breaking Football Association betting rules.
The 19 year old midfielder admitted a charge of placing 59 bets last season, five on matches involving the Championship outfit.
Stevens will be suspended until 10 October and has also been fined £1,200.
"We are hugely disappointed in the FA's choice of sanction," said Leeds chief executive Angus Kinnear.
"To prevent a young footballer from taking part in any football activities at such a critical period of his career is a disproportionate punishment following a foolish mistake from a young player.
"We are particularly disappointed that the sanction was determined by two former professional footballers who we hoped would have had a better understanding of the impact of their decision."
