WARRINGTON Wolves have been fined £2,000 by the RFL for a breach of matchday operational rules.

The breach relates to the naming of Stefan Ratchford in an amended 19-player squad, replacing Josh Charnley, for the Challenge Cup semi-final win over Hull FC on July 27.

Ratchford made his return from pectoral surgery that day but an RFL statement confirms The Wire did not inform them of their intention to change their squad.

"According to operational rules, clubs must declare their 19-player squad of players at noon two days prior to the match," the statement read.

"Subsequent changes to declared squads are permitted in the event of injuries or other exceptional circumstances, but must be supported by formal notification to the RFL.

"Amendments should be sent as soon as a club is aware that a change is required.

"The club accepts that it failed to formally advise the RFL of the amendments within the timeframes and guidelines set out."
