"Just when I thought 2020 could not get any worse Jack Goodhue cut the mullet," one user posted.
"Sad day in the rugby world as we've lost one of the greats... Jack Goodhue's mullet," wrote another.
Rugby reporter Scotty Stevenson posted, "I'm just throwing this out there: Jack Goodhue cutting the mullet may well signal the turning point in this pandemic."
The Ultimate Rugby app Twitter account went as far as creating a video to pay tribute to Goodhue's fallen mullet.
Earlier this year, Goodhue teamed up with the Bald Angels Charitable Trust and launched the Summer of the Mullet campaign which encouraged residents to grow a mullet to raise $100,000 for the Far North charity which supports at-risk youth and needy families via its various networks and programmes.
As part of the campaign, the public had their say on whether Goodhue's famous locks should stay or be shaved off but the "stay" vote won and the mullet was instead permed and dyed pink.
