Dundee United v Greenock Morton
Fourth-placed Dundee United are hosting Greenock Morton, currently one position higher in the table, this weekend at Tannadice.
The Tangerines are chasing a first win in four league games having previously won their opening trio of fixtures.
However, defender Paul Quinn (infection) is joined on the injury-list by James Keatings (dead leg), Patrick N'Koyi (hamstring) and Billy King (knock).
"Some infection has got to his (Quinn's) mouth into the abscess following the tooth extraction and it's had an effect on him," manager Ray McKinnon told the Dundee Evening Telegraph. "So we just have to wait and see what the doctors are saying about that.
"N'Koyi's still out, he's struggling with his hamstring, Keatings took a dead leg on Monday in a bounce game, which is a blow for us and he came off after 10 minutes," he continued. "Billy King hasn't trained either so we've got a couple of wee issues leading up to the game but, hopefully, a couple of them will come through that."
Falkirk's Lee Kilday is back in light training but not yet ready to return, although Robert Thomson (chest infection) and Andy Murdoch (calf) are both recovered.
