DUNDEE'S TRINIDADIAN duo of Brent Sancho and Kelvin Jack are causing concern ahead of the visit to Easter Road.
Jack is already ruled out of the Hibs game after aggravating his thigh injury during the midweek reserve clash against Motherwell.
The goalkeeper lasted less than half-an-hour before being replaced by 16-year-old Scott Murray, who will take his place as deputy to Derek Soutar tomorrow.
Sancho has been struck down by a viral complaint and was sent home from training yesterday to recuperate.
"We don't yet know the extent of Kelvin's injury but what is certain is that Scott will be on the bench on Saturday," said manager Jim Duffy.
"It is not ideal, having to have a 16-year-old as back-up, but we will just have to cope."
"After we play Hibs we have a free weekend so that will give Kelvin some time and, fingers crossed, we will get some good news regarding him."
Duffy revealed, though, that if the diagnosis on Jack is bad, then he will look to bring another keeper in as cover.
"We will wait on word about the injury and then may have to consider asking for special dispensation to bring in another goalie."
As for Sancho, Duffy speculated that the defender's demanding travel schedule - he flew back and forth to the Caribbean on international duty last week - may have something to do with what appears to be a chest infection.
"Brent has gone from the heat of Trinidad to a Scottish winter in the space of a few days and it is easy to pick up viruses when you are travelling," said Duffy.
Meanwhile, Sancho's fellow defender Tom Hutchinson, a long-term absentee because of a thigh muscle tear, has been reassured over his future.
Hutchinson has endured a torrid time on the treatment table, but manager Duffy said, "Tom is making very slow progress and is in here every day working with the physio.
" He has been very unlucky with injuries and I won't be kicking him out the door."
