FREMANTLE is fuming at the mistreatment of superstar midfielder Nat Fyfe by opposition teams.

MORE DOCKERS DEPART Freo cuts ties with young pair

Fyfe was targeted by Greater Western Sydney tagger Matt de Boer in round 14 and Dockers coach Justin Longmuir could be set to request more protection for his skipper.

"If it continues we need to follow it up, because I think he's unfairly treated to simply put it," Longmuir said on Tuesday.

"I think other mids in the comp get looked after more than him.

"It's been going on for a while and all we ask is that he gets a fair crack at it."

Longmuir says Fyfe doesn't need to draw the umpire’s attention to the situation, but said the way the dual Brownlow medallist handles his business "masks a lot of the treatment he gets".

Fremantle could be forced to make a few changes for Wednesday night's clash against Richmond, with Luke Ryan racing the clock to be ready.

Longmuir says Ryan is "improving rapidly" from a bruised hip, but if the gun defender doesn't pass his fitness test the coach may shift James Aish to cover the loss, or bring rookie Hugh Dixon in to the side for just his second senior match.

Jesse Hogan is a chance to play, but Longmuir says he'll only recall the 25-year-old in a key forward role after tinkering with the idea of playing him in defence earlier this season.
