The Giants midfielder was stretchered from the field and was seen standing after the game – but the full extent of the injury is still to be determined.
AFL clubs GWS and Sydney have been placed under strict living protocols to ensure their respective matches go ahead as planned in Round 15.
A COVID-19 outbreak in Sydney has created another headache for the league as it attempts to keep the season running as smoothly as it can.
All nine scheduled matches are expected to played this week, though some alterations could be made to timeslots to ensure some clubs can fly in and out of certain cities on match day.
The AFL could confirm a revised fixture as soon as Tuesday.
In the meantime, the Giants and Swans players are effectively housebound, aside from being allowed out for training purposes and essential needs.
GWS coach Leon Cameron said his players and football staff are “abiding by the supplementary protocols up here” ahead of their clash with Hawthorn.
“Clearly we’re preparing for a game against the Hawks on Sunday at Giants Stadium, but us and the Swans have to go through these protocols, which is absolutely correct, to make sure that the game goes on,” Cameron told Fox Footy’s AFL360.
“Hopefully the (interstate) borders can stay open and we’re there (at) 1:10pm on Sunday against the Hawks.
“I’m not a politician, but we are (optimistic).
“We’ve got a pretty good track record up here in New South Wales and lots of trust in Gladys (Berejiklian) and all the decisions she makes.
“Hopefully the other states make good decisions as well.”
Sydney are due to play against Port Adelaide at Adelaide Oval on Saturday.
The Swans could yet be placed under even tighter measures later in the week to comply with South Australian government protocols, similar to those imposed on both Geelong and Collingwood before their trips to Adelaide this month.
The AFL is also waiting on a ruling from the Victorian government on crowd capacity at Melbourne venues this week.
The AFL has applied for up to 50 per cent crowd capacity but the approved figure is more likely to be about half that.
