Motherwell boss Stuart McCall could be without up to eight players for their Scottish Premiership game against Dundee United on Friday night.
Fraser Kerr (ankle), Simon Ramsden (knee), Lee Hollis (muscle strain), Craig Moore (cracked rib) and Paul Lawson (knee) will definitely miss the trip to Tannadice.
Keith Lasley (knee ligament strain), Henri Anier (shinsplints) and Stuart Carswell, who picked up a knock in training, are rated as major doubts.
Dundee United defender Gavin Gunning could return on Friday.
The Irishman has missed several games with a knee injury but is back in training ahead of the visit of his former team.
Teenager Ryan Gauld is fighting to shake off a niggling hip injury in time to face Well.
