BRISBANE has flown four players into Victoria on Monday to join the current squad ahead of Thursday's rescheduled match against Collingwood at Marvel Stadium.
Darcy Gardiner, Rhys Mathieson, Marcus Adams and Connor Ballenden have all landed in Melbourne and will isolate away from the group until the return a negative COVID-19 test result.
The reinforcements bring the total number of Lions players to 28 following the recent COVID-19 outbreak in Greater Brisbane that has forced a three-day lockdown in the region.
Ruckman Oscar McInerney underwent scans on his injured ankle on Monday and is awaiting results, while midfielder Jarrod Berry joined Monday's training session at Port Melbourne after being a late withdrawal against Geelong with a hamstring niggle.
Lions captain Dayne Zorko said it was a relief to have some clarity, adding that the Lions' preparation for the Magpies had not been compromised.
"We've stuck to our routine as if we would if we were in Brisbane," he said.
"Yesterday was a day off in the schedule for us and today we were able to get everything we needed, done."
Meanwhile, Gold Coast will get out of Queensland early and fly on a chartered plane to Adelaide on Tuesday three days out from its clash with the Crows on Good Friday.
The Suns are hopeful their trip will be short-lived but are aware it could get extended and involve further stops depending on Queensland's COVID-19 situation.
The AFL is yet to clarify whether Brisbane will remain in Victoria after Thursday night's clash, given the Lions play the Western Bulldogs in Ballarat the following Saturday, or whether they return to Queensland.
However, speaking on Monday, the League's general manager of broadcasting and clubs Travis Auld revealed Collingwood's looming round five fixture against West Coast at Optus Stadium was one of the key reasons the upcoming contest was altered.
"Collingwood plays West Coast on the 16th of April on a Friday night," Auld said.
"If they were to play in Brisbane, there were potentially some issues around their ability to get into Western Australia and needing to quarantine. We were still working through that up until this morning.
"By keeping Brisbane here and by Collingwood not going to Brisbane, it eliminated that issue.
"If they (the Lions) want to bring players in, the restrictions start at 5pm (on Monday). But we would be really careful in the sense that if they fly players in, they would be isolated away from the group and would get tested.
"They won't be introduced to the group until they're really clear that those test results are back. Yes (they can bring players in), but there will be an abundance of caution."
Coach Chris Fagan said the travelling squad was in a positive frame of mind despite the disruption of the past few days.
"They've all got smiles on their faces and looking forward to the opportunity," he said on Monday morning.
"I brought four pairs of jocks with me so I need to find a laundry today. But, no, we'll do whatever's required."
The Lions were preparing to fly out of Victoria at 11am AEDT on Sunday morning before they were told they'd be required to stay at least another day.
All players, coaches and officials have returned negative readings for COVID-19 after being forced into tests following the loss to the Cats at GMHBA Stadium.
In a statement, Auld said: "In the interest of the health and safety of both clubs and the wider community we have made the decision move the match to Marvel Stadium.
"Marvel Stadium was the scheduled venue for the return match between these two clubs later in the season, which made the decision to switch the venues as per the fixture the appropriate choice.
"As we continue to navigate the ongoing pandemic, we are constantly ensuring we have the contingencies in place to best combat any challenges that are presented. On behalf of the AFL I would like to thank both clubs for their patience and understanding of the evolving situation."
Auld said fans who had purchased tickets to the Gabba match in round three would receive a full refund or the opportunity to use their tickets for the Round 22 return match.
Tickets for the Marvel Stadium match Thursday will go on sale on Tuesday. Details to be confirmed shortly.
