Crystal Palace have been fined up to £25,000 for breaching a Premier League "good faith" rule at Cardiff City last season.
Bluebirds owner Vincent Tan accused Palace's former head of recruitment Iain Moody of trying to get team news ahead of the Premier League clash in Wales on April 5.
Palace went on to win the relegation six-pointer 3-0, and the then-manager Tony Pulis immediately denied the claims.
He said, at the time: "You look at it, for three weeks we have picked the same formation and same team, we haven't changed anything.
"Irrespective of who or where it has come from it is pure speculation until the team-sheet comes in.
"Although I try and avoid it myself, I have known managers change the team 10 minutes before the team sheets have gone in so it is very difficult to say it is definitely going to be that team."
