The MRC suspended Addin Fonua-Blake for one game and issued four fines after Sunday's matches.
The MRC has concluded Round 23 by issuing one suspension and four fines following the matches on Sunday.
Addin Fonua-Blake, a prop for the Cronulla Sharks, faces a one-game suspension after being charged with a Grade 2 Careless High Tackle on St George Illawarra Dragons' forward, Hamish Stewart.
Fonua-Blake received a sin bin penalty in the last 15 minutes of the Sharks' match against the Dragons, which enabled St George Illawarra's Setu Tu to score a late try, securing a 24-16 victory for his team.
If Fonua-Blake chooses to contest the charge at the judiciary and is found guilty, his suspension could extend to two matches.
