St Johnstone goalkeeper Alan Mannus has been ruled out for six to eight weeks at least after fracturing a bone in his thumb.
Saints confirmed on their official website that the Northern Ireland international sustained the injury in training to deliver a heavy blow to manager Tommy Wright's plans.
Following the postponement of the Saints' Scottish Premiership clash with Dundee United at Tannadice on Monday night, Mannus was due to serve the second of his two-match suspension in the Scottish League Cup semi-final against Aberdeen at Tynecastle on Saturday, but will now be out until March at least.
Unless Wright brings in another keeper before the transfer window closes on Friday, 41-year-old player-coach Steve Banks will continue between the sticks.
Wright said: "Alan damaged his thumb in training on Monday.
"At this stage we don't think he will need an operation, but he will see a specialist later in the week and we'll have more information after that.
"However, we are looking at six to eight weeks absence as a minimum."
