Sharks prop Chris Heighington was one of three players charged so far in Round 1.

Forwards Chris Heighington and Pauli Pauli have both been suspended for Round 2 of the NRL season, as two of three players cited by the NRL match review committee in Round 1.

Heighington entered an early guilty plea to a grade one dangerous throw for his challenge on Cowboys counterpart Ben Hannant on Saturday night. 

On his Knights debut, Pauli was slapped with a grade one dangerous contact charge for his challenge on Leivaha Pulu late in the Titans' win over Newcastle. He also entered a guilty plea and will miss this week.

Also attracting the scrutiny of the match review committee in Round 1 was Roosters captain Jake Friend, who won't miss any game time after accepting an early guilty plea for his grade one dangerous contact – head/neck charge.
