ESSENDON chief executive Xavier Campbell has tested positive to COVID-19, but the bombshell diagnosis won't affect the club's training plans.

Campbell developed mild symptoms on Monday afternoon and immediately got tested. The positive result was confirmed on Tuesday morning.

The fully-vaccinated Campbell is now isolating and will continue to follow the Victorian Government guidelines and quarantine protocols.

Given Campbell has not attended the NEC Hangar since last Wednesday and has had no direct contact with the club's football program under the AFL's football department protocols, his positive test isn't expected to affect the Bombers' training plans.

"I experienced very mild symptoms on Monday afternoon and out of caution, got tested which has since returned a positive result. My family and I are now isolating as we await all results," Campbell said.

"Importantly, our football program has not been impacted and can continue training as normal. I will continue to work from home throughout my quarantine period."

As a precautionary measure, Essendon has asked all administration to be tested and await a negative result before returning to the office.
