The Rugby Football League have charged eight players from Round 20 of Super League, including three from London Broncos' clash with Warrington Wolves which ended in the capital side being relegated.
The trio in trouble from Sunday's fixture at the Halliwell Jones Stadium are all called on the same charge of striking after a 21st-minute fracas.
Broncos prop Olsi Krasniqi and Wolves centre Chris Bridge have been punished with Grade A striking while London forward Atelea Vea has been charged with a Grade B offence.
Gareth Hock of Salford Red Devils has been charged with the Grade E offence of making deliberate physical contact with a match official in the first half of their showdown with Hull FC on Saturday.
Catalan's Vincent Duport has been hit with a Grade D offence of making dangerous contact with Wigan winger Josh Charnley, while fellow Dragon Gregory Mounis will face a Grade C charge of a dangerous throw, made on Warriors player John Bateman in the same match.
Widnes Vikings' Phil Joseph has been charged with making Grade B dangerous contact on Wakefield Wildcats second row Taulima Tautai in the televised game last Thursday, while Vikings centre Stefan Marsh faces a Grade A charge for making dangerous contact with Reece Lyne.
All eight players were charged after the incidents were viewed by the RFL Match Review Panel, which also issued a formal caution to Widnes forward Hep Cahill for raising the knee during a tackle.
Joseph, Marsh, Bridge, Krasniqi and Vea have until 11.00am on Tuesday to submit Early Guilty Pleas. Hock, Duport and Mounis do not have the option of submitting an EGP and will face an independent disciplinary tribunal on Tuesday.
