Dylan Levitt faces a fitness race to star at Rangers next weekend after being injured in the warm-up of Dundee United’s defeat to Livingston.
The Tannadice talisman was initially named in the United starting XI for the 1-0 loss to Livi but pulled out at the last minute.
Declan Glass took his place in the United side and turned in a man-of-the-match display.

But it now seems highly unlikely Levitt will be fit to face Gers.
The exclusion of Levitt will be a further blow for United who are also likely to be without French striker Max Biamou.
Biamou has yet to start for United since moving on a free transfer from Coventry City in October. He is struggling with a foot injury.
But long-term injury Marc McNulty could force his way into the Ibrox reckoning with United keen to arrest a run of one win in eight games.
When asked about Levitt’s injury, Courts said: “It seems to be a reoccurrence of the same injury.
“He was injured in the warm-up. There’s no doubt Dylan makes us a better team.
“But Declan came in and showed us what he’s about and won man of the match.”
Tam Courts: Livingston’s penalty was harsh
Meanwhile, Courts was left frustrated by the decision to award Livi a penalty for the Jeando Fuchs challenge on sub Andrew Shinnie.
Ayo Obileye converted from the spot to clinch the win for Livingston.
“It looked very harsh from where I was standing,” added Courts.
“Jeando seemed to be in control and just seemed to go shoulder to shoulder with their player.

“Livi players are streetwise and the ref pointed to the spot.
“We seemed to be on the wrong end of a few 50/50 decision today which is frustrating.
“I’m not normally one to complain about refs but I thought there were a lot of innocuous coming togethers.
“That affected our rhythm and it became quite frustrating for us.”
