Pangai Junior has been charged with a grade one offence for the incident involving Murray in the 26th minute of Thursday night's clash between the Broncos and Rabbitohs.
The Bunnies ended the evening victors to the tune of 46-0 at Suncorp Stadium, with Pangai Junior's charge souring the Queensland club's evening.
Pangai Junior will miss three weeks of action with an early guilty, with the lengthy charge coming due to his judiciary record over the past two seasons.
