DECLAN Patton has not been banned after an allegation of biting was made against him by Hull FC's Ligi Sao.

However, the RFL's Match Review Panel have referred the incident for further investigation.

The Black and Whites prop alleged the Wire scrum-half bit him just before Mike Cooper scored Warrington's first try in Friday's 37-12 victory, with referee Ben Thaler putting the incident on report.

However, Patton has not been handed a penalty notice and will be available for Thursday's clash with Castleford Tigers.

The minutes of the panel meeting say: "Opponent reacts at the closing stages of the tackle. Opponent has arm around the neck/head area of player. Reported immediately to the referee. Footage inconclusive. Referred for further investigation."

Indeed, it is Sao who appears on the disciplinary sheets – he has been hit with a one-match penalty notice for Grade B dangerous contact for the "crusher tackle" that preceded his allegation.

Wigan's Ben Flower has been given a two-match ban for the same charge while St Helens' James Bentley will not serve a suspension despite a Grade A dangerous contact charge.
