Chelsea have been criticised by football's equality group Kick It Out for keeping their punishment of John Terry secret.
The club said they had taken "further disciplinary action" against the defender after Terry decided to accept a four-match ban and £220,000 fine from the FA for racially abusing QPR's Anton Ferdinand.
But Chelsea said they would be keeping their action "confidential" due to club policy.
Lord Herman Ouseley, chairman of Kick It Out, said that stance could damage Chelsea in the eyes of those people who had been waiting many months to see how the club handled the case.
