Ciaran Coll is the latest Finn Harps player to be facing some time on the sidelines after he suffered a serious injury against Dundalk on Friday night.
The defender was stretchered off in the dying moments of the game at Oriel Park which Harps lost 3-0.
He was brought to hospital in Drogheda and will receive further scans on a knee problem this week.
Barry Molloy and Sean Houston were injured in Harps' opening game against Derry City and are also likely to miss a number of weeks.
Ollie Horgan's side are back in action on Monday night when they host Shamrock Rovers at Finn Park (8pm).
