Slater has been charged with a grade one dangerous throw, while Wiki faces a grade five charge for dropping knees. If unsuccessful, Slater will be suspended for two games and WIKI eight.
Meanwhile, Wests Tigers coach Tim Sheens has rejected Wayne Bennett's claim that the NRL risks chaos with a trend for referees to blow fewer penalties. Bennett was scathing after watching whistleblower Shayne Hayne call only two penalties during Brisbane's 23-18 win over the New Zealand Warriors.
But Sheens has backed an edict from referees boss Robert Finch and his assistant Bill Harrigan for referees to be more lenient in the opening exchanges to let the games flow.
Elsewhere, Anthony Mundine has quashed rumours of a return to the rugby league field despite reports he was set to play for a regional NSW side.
Three Ways United, a mainly Aboriginal Group 17 rugby league club in Griffith, was hoping Mundine would make a one-off appearance for them in the coming months to help boost the game in country NSW.
The Area News in Griffith reported that Mundine was keen to make an appearance alongside his childhood friend and former Dragons teammate Robbie Simpson, the club's captain-coach, but Mundine laughed off talk of a comeback.Like
