Manly youngster Corey Waddell is facing a possible three-match ban for his strike on Penrith's Liam Martin in the 30th minute of their clash on Thursday night.
The rookie will receive a two-match ban if he pleads guilty to the grade-one striking offence, but could miss three matches if he unsuccessfully challenges the ban at the judiciary.
In other news, Panther Tyrell Fuimaono was hit with a grade-one careless high tackle on Curtis Sironen, and is looking at a fine between $1150-$1500.
