Essendon defender Conor McKenna’s fourth COVID-19 test has come back negative, according to Seven News’ Tom Browne.

The news is unlikely to affect his situation but adds intrigue to it after his two previous tests returned low-level positive results.

McKenna is currently in quarantine until July 4, with the Victorian health department deeming James Stewart was the only teammate he came in close contact with.

The rest of Essendon’s team and staff returned negative results including Stewart, however, the big man has also been made to isolate.

“This has clearly been a sensitive and delicate matter, and as a club, the health and wellbeing of our players and staff, particularly Conor and James, has been our number one priority throughout this period,” Essendon chief executive officer Xavier Campbell said earlier today.

“The public nature of our industry has made this task even more difficult but we are now pleased to have reached an outcome with the DHHS.

“On behalf of the club, I also wish to thank the Department of Health and Human Services for their significant work in recent days and for providing this information in a timely and professional manner.

“The players will formally recommence training on Wednesday morning at the NEC Hangar in preparation for our round four game against Carlton on Saturday night.”

Essendon’s clash with Melbourne last Sunday was postponed following McKenna’s positive test, with the matchup now set to be squeezed into the upcoming fixture.

The Bombers face Carlton this Saturday night at the MCG at 7.40pm (AEST).
