Walyalup captain Alex Pearce has been handed a three-match suspension for rough conduct against Yartapuulti's Darcy Byrne-Jones.
The incident occurred in the second quarter of Saturday night's Sir Doug Nicholls Round 11 clash at Optus Stadium and has been graded as careless conduct, severe impact and high contact.
The Club has until 10am WST on Tuesday 27 May to decide whether to accept the MRO decision or challenge it at the AFL Tribunal.
Three other Walyalup players have also been charged by the MRO following Saturday night, including Andrew Brayshaw, Caleb Serong and Neil Erasmus.
Brayshaw has been charged with an attempted trip against Ollie Wines in the third quarter. He can accept a $1,500 sanction reduced to $1,000 with an early plea.
Serong has been offered a fine for making contact with an umpire, while Erasmus faces a financial sanction for rough conduct against Yartapuulti tagger Willem Drew.
