Warrington forward Ben Westwood has been charged by the RFL following his Grand Final clash with Wigan's Blake Green.
Westwood has been ordered to face a disciplinary panel on Tuesday accused of a Grade B punching offence during his side's Old Trafford defeat.
Television replays showed the Wolves star catching Green with a blow to the head, but Westwood later claimed he could not remember the incident.
The Daily Mirror on Monday quoted him as saying: "I didn't really know much about it. I haven't seen it so I don't know what to say.
"I didn't know I punched him. We'll have a look at it and see what the review panel says."
Westwood, who is due to join up with England for a pre-World Cup training camp in South Africa, could now face a ban.
The second-rower scored a try for the Wolves in Manchester, helping to give them a 16-2 lead. However, Wigan hit back with 28 unanswered points to lift the title.
