Former England full-back Delon Armitage has been cited for an alleged tip tackle during Toulon's Heineken Cup defeat against Montpellier on Saturday.
Armitage was yellow-carded by referee Alain Rolland following the first-half incident.
European Rugby Cup announced that Armitage will face a disciplinary hearing in Dublin on Thursday.
Former London Irish player Armitage, 29, has a chequered disciplinary record. At the start of 2011 he received an eight-week ban for pushing a doping officer and using abusive language when asked to provide a urine specimen after a Premiership game.
And that was followed the same year by suspensions for striking an opponent during a league match, a dangerous high tackle on Bath wing Tom Biggs and for a high tackle during England's final pool fixture of the 2011 World Cup against Scotland.
Armitage, capped 26 times by England, has been reported by citing commissioner Shaun Gallagher.
The range of punishments for tip tackles vary between four weeks at the low end to a top end punishment of 52 weeks. Despite Toulon's loss to Montpellier, they still finished as Pool Six winners and will play Leicester in the quarter-finals on the opening weekend in April.
ERC have also announced that Rovigo forward Jean Francois Montauriol has been cited for allegedly stamping or trampling on Perpignan lock Guillaume Vilaceca in last Thursday's Amlin Challenge Cup encounter.
Racing Metro flanker Antoine Battut, meanwhile, will face a disciplinary hearing on Thursday following his sending off for striking a Munster player with his knee at Thomond Park yesterday.
And Rovigo centre Joe van Niekerk will join his team-mate Montauriol on Thursday after being red-carded following an alleged tip tackle in the Perpignan game.
