The midfielder didn't risk an extra week on thesidelines by fighting his case, but he will now be lumped with 76.25carryover points for the next 12 months as a result of the failedchallenge.
The Dockers have two big games to round out theseason – against the Brisbane Lions at the Gabba and Port Adelaide atPatersons Stadium – as they seek to lock in a top-four spot.
AfterTuesday night's case, which was conducted via video link, Fremantlefootball manager Chris Bond said the club was assessing its options.
The Match Review Panel classified Fyfe's strike on Hawthorn midfielder Jordan Lewis as intentional, low impact and high contact.
Fremantle accepted the classifications of low impact and high contact but unsuccessfully argued it should be graded reckless conduct instead of intentional.
Represented by Nick Tweedie SC, Fyfe conceded he intended to strike Lewis, but he did not intend to strike him high.
After making contact to Lewis's shoulder, he said his arm slid up and into the Hawk's neck, resulting in accidental high contact.
"I wanted to make contact to his chest plate and his arms," said Fyfe, who described the hit as an "arm bar".
"I intended to stop his run and give me a chance to get goal side of him."
In an unusual case, Tribunal chairman Ross Howie overruled Fremantle's challenge and jury members Wayne Henwood, David Neitz and David Pittman were not required to set a penalty.
Howie ruled that the only point of contention was whether Fyfe intended to strike - which he admitted he had in evidence - not whether he intended to strike Lewis high or to the body.
He outlined that determination at the beginning of the case, at which point it was open to Fremantle to change Fyfe's plea to guilty and receive a discounted penalty, which would have ruled him out for two matches with 7.19 carryover points.
However, the Dockers pushed on in what was essentially a futile challenge, and the young star will now have to carry 76.25 carryover points on his record for the next 12 months.
