Saracens flanker Mike Rhodes will face a European Professional Club Rugby disciplinary hearing following an incident in the recently concluded Heineken Champions Cup game against Leinster.
The 32-year-old was cited by citing commissioner Beth Dickens (Scotland) for an alleged strike on Leinster centre Robbie Henshaw with his head in the early stages of the game.
The punishment for striking with the head with low-range sanction is six-week ban while for mid-range the suspension will be 10 weeks and for high range it will be between 16 to 104 weeks.
If Rhodes is proved guilty, then the news will be a big blow for Mark McCall's side ahead of their semi-final game against Racing 92 as they are already without England captain Owen Farrell, who is currently on a five-week suspension.
"Rhodes is alleged to have committed an act of foul play in that he struck the Leinster centre, Robbie Henshaw (No 12), with his head in the second minute of the match in contravention of Law 9.12.
"An independent disciplinary committee comprising Simon Thomas (Wales), Chair, Frank Hadden (Scotland) and Val Toma (Romania) will hear the case by video conference on Tuesday, September 22."
