St George Illawarra second-row forward Joel Thompson is set to miss the Round 11 Telstra Premiership clash with the Rabbitohs after being charged by the NRL Match Review Committee.

Thompson has been charged with a grade one careless high tackle on Canberra's Blake Austin in the Dragons' golden point win at UOW Jubilee Oval on Thursday night.

The base penalty for that charge is 75 points, which means a player would not usually miss any games. However Thompson has two prior similar offences in the past two years, both carrying 50 per cent loadings, which take his charge to 150 points. Even with an early guilty plea, which allows for a 25 per cent discount, Thompson would still have 112 points and would miss one game.

Thompson also has 52 carryover points from a previous charge.

The Dragons have until noon on Tuesday to enter a plea.
