Samoa duo Rey Lee-Lo and Motu Matu'u have been cited following their yellow card incidents during the recently concluded World Cup clash against Russia at Kumagaya Rugby Stadium.
Both Lee-Lo and Matu'u were sin-binned in the 28th and 30th minutes respectively but despite the setback, Samoa went on to win the encounter with a 9-34 margin.
Lee-Lo was sin-binned by referee Romain Poite after consultation by TMO Graham Hughes after he struck with his shoulder on the head of Vasily Artemyev while Matu'u also was involved in an incident involving the Russian skipper.
Both the players have been charged for a breach of Law 9.13 that deals with dangerous tackles and will attend a hearing in Tokyo.
"This remains on his disciplinary record in the event that he accumulates any combination of three warnings or yellow cards during the tournament," read a statement from World Rugby.
Meanwhile, Samoa number eight Afaesetiti Amosa has been ruled out of the remainder of the tournament after sustaining a knee injury during the game against Russia.
Amosa, who came off the bench at the start of the second half scored a try in the 45th-minute following which he was immediately forced off the field.
"We are absolutely gutted for him. He is upbeat - but we just need to do what's best for Afa," said Manu Samoa coach Steve Jackson.
