St Mirren's squad have been released from quarantine as they prepare for their first Scottish Premiership game in over a month.
The Buddies were forced to postpone their clashes with Motherwell and Hamilton after a Covid-19 outbreak, but Jim Goodwin's men are now back in training ahead of Friday night's Paisley showdown with Dundee United.
St Mirren could hand debuts to new signings Jake Doyle-Hayes and Brandon Mason, but Ryan Flynn is still short of fitness despite re-joining his team-mates after a long-term knee injury.
Marc McNulty is back in contention for Dundee United.
The striker, on loan from Reading, returned to training after recovering from a hamstring strain which kept him out of the win over Ross County last weekend.
Defender Mark Connolly will resume training on Monday as he manages a knee problem.
