Cronulla hooker Michael Ennis has been found guilty of a Grade 1 careless high tackle at the NRL Judiciary on Wednesday night.

The charge means he will miss Cronulla's Round 17 clash against the Sea Eagles at Brookvale Oval on Sunday afternoon.

Ennis could still be a late call up to the NSW Origin team however, as his suspension will officially be served after Round 17 is complete on Monday night. 

NSW hooker Robbie Farah joined NSW camp on Wednesday night, but it is unclear whether he'll be right to play the Origin decider at Suncorp Stadium on July 8, after having surgery on his fractured right hand.

Ennis will make the trip to Coffs Harbour to join the Blues squad as cover for Farah. 

St George Illawarra forward Will Matthews was also unsuccessful at the judiciary. Matthews was found guilty of his grade one dangerous throw charge on Eels forward Anthony Watmough, andwill serve a one match suspension. 

Four other players were charged by the match review committee including Warriors prop Charlie Gubb (grade one dangerous contact), Cronulla's Matt Prior (grade one dangerous contact) and Wests Tigers pair Delouise Hoeter (grade one Dangerous Contact) and Luke Brooks (grade one contrary conduct).
