Fremantle defender Alex Silvagni has been referred directly to the AFL tribunal for contact on West Coast’s Jamie Cripps during the second quarter of Sunday’s Carlton Draught Derby.

Fremantle coach Ross Lyon said he did not see the incident.

"Well, there are two things," Lyon said.

"Once he is up before a tribunal, I have an inability to comment.

"And secondly, I didn't see it."

Cripps suffered an injured jaw but managed to return in the third quarter.

West Coast coach Adam Simpson said his small forward was very sore.

"Crippa's got probably a fractured jaw," Simpson said post-match.

"We wouldn't have put him back on if it was a broken jaw. But there might be a fracture there. He's pretty sore at the moment.

"I deliberately didn't watch it. But I've heard a lot about it."

The loss to West Coast was Silvagni’s second game for Fremantle this year.

Lyon also indicated post-match that defenders Zac Dawson (suspension) and Luke McPharlin (calf) will be available for selection this Sunday against North Melbourne.

Meanwhile, West Coast's Chris Masten has also been referred to the tribunal after Fremantle's Nick Suban claimed he had allegedly been bitten by the Eagles midfielder.

The tribunal will sit Tuesday night.
