Dundee United could have defender Garry Kenneth back for the visit of Celtic on Sunday.
The former Scotland Under-21 man was ruled out for up to eight weeks with a groin problem only 10 days ago but has made rapid progress and returned to light training on Thursday.
He will not be in contention to start the game but if he comes through another session on Saturday then manager Craig Levein will consider him for the match day squad.
Long-term injury absentees Jon Daly (knee), Francisco Sandaza (groin), Kevin Smith (ankle), Lee Wilkie (knee) and Scott Robertson (groin) are all missing.
Celtic skipper Stephen McManus is suspended while manager Tony Mowbray is still without long-term crocks Artur Boruc, Scott Brown and Shaun Maloney.
Josh Thompson may make his debut if Glenn Loovens, who had to come off with a groin strain in the 3-3 draw with Falkirk in Celtic's last game, fails to recover.

Dundee Utd (from): Weaver, Dods, Kenneth, Dillon, Dixon, Kovacevic, McCord, Myrie-Williams, Swanson, Buaben, Gomis, Conway, D Robertson, Cadamarteri, Goodwillie, Shala, Casalinuovo, Banks.
