Lee Wallace is facing a further spell on the sidelines through injury.
The Sevco skipper hasn’t played since September after suffering a groin injury against Partick Thistle.
The initial verdict was that he would be out for seven or eight weeks but the 30-year-old has been unable to shake the injury off.
Graeme Murty had hoped to have the defender available for the match with Celtic on December 30 but over three months later Waldo has still to return to competitive action.
“He had a flare up from a small procedure to try and alleviate some tension in his groin,” the caretaker Sevco boss told the club tv service.
“We are hopeful of getting him back onto the grass this week but obviously it is a time where his body is telling him some signals that aren’t great for us.
“So we have to take our time with him and make sure we respect the athlete and get him back onto the grass and give him a load that is commensurate to his level and give him something that he is capable of doing.
“Basically, he had an injection into some scar tissue to try and break that up and sometimes you get a flare from that and increase your sensitivity and increase your irritation around that area, which isn’t nice to play with.
“But we are hopeful that in the next couple of days that will start to settle down and he can start to increase his load again.”
Sevco have still to make any comment on the calf injury that Josh Windass suffered in the 2-2 draw with Motherwell on Saturday.
The former Accrington starlet has been Sevco’s top scorer since the turn of the year with Murty building his side around Windass.
If he fails to make it in time for Saturday’s match with Dundee Jason Cummings is the likely replacement with the on loan Nottingham Forest striker hoping to get his first ever top flight goal.
