Linfield may have to review their traditional opposition to playing football on a Sunday should the champions progress in Europe, says David Healy.
The Blues face Maltese side Floriana in the Europa League at Windsor Park on Thursday night, with two more rounds before the group stages if successful.
Linfield missed out on the group stages on away goals last year.
With Europa League games played on a Thursday, it would be a pragmatic step for the Blues to change their articles to challenge on both a European and domestic front.
"The main concern is if an Irish League club does ever reach the group stages in European competition, games will be played on a Thursday night with Danske Bank Premiership games due to be played the following Saturday," explained Healy.
The Blues chief added: "Linfield don't play on Sundays, or haven't played on Sundays. We haven't been hindered in our league campaigns long-term because we haven't reached the group stages, no Irish League club has.
"Europe hindered the start of last year's domestic campaign, we lost 4-2 to Coleraine in between playing Sutjeska and Qarabag and Oran Kearney came out after and said the game should probably have been postponed, because not only was Europe important to Linfield, it was important to the whole Irish League to improve the coefficient.
"If we were to get to the group stages, therein lies a problem because we are still going to have 38 league games and three cup competitions.
"There have been discussions about the possibility of change, but that needs to be decided by the members of the club if that is the case."
Chairman Roy McGivern explained: "The Linfield board passed a motion earlier this year to allow home games on a Sunday in exceptional circumstances. Nothing has changed yet because while the motion was passed at board level, it must now be put to our members before our position changes on the subject.
"We had hoped to do that at our Annual General Meeting in May, but obviously that was postponed due to coronavirus and we are waiting to rearrange that AGM. If results go our way in the Europa League and we were to reach the group stages, then we would have to bring forward our AGM as soon as possible. We have considered holding the AGM online, but with 600 members that would be very difficult if not impossible.
"So we are now looking at holding our AGM outdoors at Windsor Park, with social distancing, if the need arises."
