West Coast has accepted the one-match sanction issued to Deven Robertson for rough conduct in Sunday’s win over Port Adelaide.

The West Coast midfielder was cited for his tackle on Zak Butters during the third term, with the incident graded Careless Conduct, Medium Impact and High Contact, with no option for an early plea. 

Robertson will miss the Eagles' round four clash with Sydney at Optus Stadium on Saturday.

Co-captain Liam Baker has accepted a $1000 fine for engaging in a melee/wrestle, downgraded from $1500 with an early guilty plea.
