The 27-year-old reported feeling nauseous and dizzy during the match at Adelaide Oval and was subbed out of the game at halftime.
He was taken to hospital, where he spent Thursday night, and was diagnosed with a heart irregularity.
“(Wines) will remain under observation over a heart issue that emerged during Thursday night’s game against Melbourne,” the club said.
“The Brownlow Medallist was discharged this evening after a heart irregularity resolved itself.
“The 27-year-old is feeling well and will remain under observation over the coming days.”
Wines is not the first AFL player to be diagnosed with a heart irregularity.
In 2018, there were two frightening on-field incidents with St Kilda’s Dylan Roberton and Collingwood VFL player Kayle Kirby both collapsing due to irregular heartbeats.
Carlton ruckman Matthew Kreuzer also suffered a heart irregularity during a match, while teammate Caleb Marchbank was taken to hospital with an elevated heart rate that same year.
At the time, Richmond premiership star Jack Riewoldt suggested players undergo mandatory heart testing in a bid to avoid the “scary” scenario Roberton faced.
“The vision of him looking blankly into the air with glassy eyes is the scariest thing I reckon I’ve nearly seen on a footy field,” Riewoldt said on AFL360.
“The sad thing is I think it’s more prevalent than what people actually know about. At local football, there’s a really big push to have ... defibrillators at every ground due to heart conditions and undiagnosed murmurs and other issues that can pop up like Dylan’s did on the weekend.”
Wines’ diagnosis comes just weeks after vision of Western Bulldog Hayden Crozier being hooked up to an ECG machine in the change rooms was broadcast nationally when fainted during a match.
