Fremantle midfielder Matt de Boer has revealed that the ankle injury which kept Nat Fyfe out of Saturday's loss to Adelaide happened while the star was playing with a football in his hotel room.
The Dockers will today learn the extent of the injury which threatens to sideline him from the team's run to the finals.
Forward Chris Mayne is expected to face a concussion test after being subbed out of the match following a knock to the head but defender Alex Silvagni will be available after being withdrawn from the game with illness.
The ninth-placed Dockers will welcome back key defender Luke McPharlin from suspension for Saturday's game against Richmond.
Fyfe would have added significant skill to the midfield which was thrashed in the clearances. He had been influential in the previous two games after returning from 12 matches on the sidelines with a shoulder injury.
De Boer said Fyfe tripped over a bag just hours before the game.
"It was just one of those freak accidents. He's always got a footy in his hands and he was just getting his touch ready on game day and he slipped on a suitcase," de Boer said.
"I'm sure he annoyed his mum at an early age breaking glasses. He's handling the football all the time.
"We're a very resilient team and we've played without Fyfey for the majority of the year. It was a shock initially but we moved on pretty quickly."
De Boer said he spoke to Mayne when the team arrived back in Perth and he appeared fine.
But with more players missing games the week after suffering a concussion, Mayne is no certainty to play against the Tigers.
Fremantle coach Ross Lyon flew to Victoria to watch Richmond thrash the Western Bulldogs at the MCG yesterday.
He criticised his players for allowing too many easy goals in the absence of McPharlin. But he was also angered by some needless 50m penalties during the tight match.
"I thought discipline at critical times in the game we gave four 50-metre penalties away," he said.
"Were they all there? I'm not sure, but they're a big penalty and they kicked 1.3 from those things. So that was quite costly as well."
Lyon was then coy on whether he thought the penalty was too harsh in relation to the severity of the misdemeanours.
"The penalty is 50. You'll have to go to the rules committee and make a submission if you want a change," he said. "But I think that's the rule, last time I looked."
The Dockers have now spent the past six weeks outside the eight by just percentage. The team fell out of the eight in round nine and must keep winning to keep its finals hopes alive, although the same applies now to Essendon after their loss to North Melbourne yesterday.
The eighth-placed Bombers are only 1.47 per cent ahead of Freo.
De Boer said the players welcomed the challenge.
"The boys go out there every week knowing that football mortality is out there. We've got to front up each week and put our best foot forward," he said.
