Ulster coach Neil Doak is hopeful of mounting a strong defence in the appeal against Iain Henderson’s red card.
The flanker was dismissed late in Ulster’s 23-23 draw with Munster and will appear before a disciplinary hearing in Wales on Wednesday.
Doak said: “There was no malice on Iain’s part and certainly he did not intentionally clear anybody out with the head as was claimed by the referee.
“We have a few bits and pieces we’re looking at in defence of that.”
Henderson could receive a sanction ranging from nothing (red card deemed sufficient) to a season ending ban.
