England prop Joe Marler has been cited after he appeared to grab Wales captain Alun Wyn Jones' around the groin area during his side's 33-30 Six Nations victory on Saturday.
After just 10 minutes of the Twickenham game a melee broke out when Wales had a try disallowed for a George North knock-on, and the incident was caught on camera.
Jones called officials to review the incident in his post-match comments, with Marler now having been cited, Six Nations have announced.
It said in a statement: "Joe Marler has been cited for an alleged infringement of Law 9.27 (a player must not do anything that is against the spirit of good sportsmanship -- hair pulling or grabbing; Spitting at anyone; grabbing, twisting or squeezing the genitals (and/or breasts in the case of female players) during the Guinness Six Nations England v Wales match last Saturday."
Teammate Courtney Lawes has been cited for a dangerous tackle, while Manu Tuilaigi, who received a red card for a high-tackle on Wales wing George North, also faces a disciplinary.
A disciplinary hearing for the three England players will take place in Dublin on Thursday.
Two of the final-round games in this year's championship have been postponed indefinitely-- including France vs. Ireland and Italy vs. England -- due to the coronavirus outbreak. Wales' finale against Scotland is scheduled to go ahead as planned.
