Fremantle captain Nat Fyfe has defended star Michael Walters, saying AFL opponents are terrorising him off the ball.

Walters was charged with headbutting Melbourne youngster Jay Lockhart during Saturday’s loss at the MCG.

Soon after the third-quarter incident, Melbourne co-captain Nathan Jones remonstrated with Walters and that led directly to a Fremantle goal.

Walters was among Fremantle’s best again against the Demons, kicking three goals.

“What people don’t understand about ’Sonny’ is he gets so much niggle off the ball - people terrorise him all game,” Fyfe told Channel Seven’s Game Day.

“For him to be able to play the sort of footy he is, (it) is a credit to his preparation.”

Walters’ clash with Lockhart is among several incidents from round 14 that will keep match reviewer Michael Christian busy on Monday.

West Coast defender Jeremy McGovern already faces a one-game ban for rough conduct, after the incident where Essendon’s Matt Guelfi ended up hitting the Optus Stadium fence.

There is speculation that the Eagles will take the charge to the tribunal.

Fremantle’s Ed Langdon will come under scrutiny for an incident where he tangled with Jayden Hunt and his knee ended up on the Melbourne player’s head.

Port Adelaide speedster Karl Amon could be in trouble for a collision that left Geelong forward Gary Rohan with concussion.

The AFL’s thorny issue of gut punching will be in the spotlight again when Christian looks at a clash off the ball that left Geelong veteran Harry Taylor doubled over.
