Essendon defender Conor McKenna has been handed a one-match ban for breaching COVID-19 protocols, reports The Age.

In good news for the Bombers, the Irishman has already served his suspension in the club's one-point loss to Carlton on Saturday night.

McKenna has reportedly been released from quarantine today and is available for selection for Friday night's clash against Collingwood at the MCG.

The 24-year old was reportedly found to be in minor breach of the protocols when he visited his former former host family on Friday afternoon, June 19.

He was tested before visiting them on Friday morning, with the results coming out on Saturday morning.

The league is expected to announce McKenna's suspension later today.

The Bombers' Round 4 clash with Melbourne from the weekend he tested positive was postponed and will now be player at a later date.
