Latest news on OS is that Craig's injury isn't as bad as first thought though he definitely won't play tomorrow and Doolan has recovered well enough to be considered for the squad tomorrow.
On the down side Welsh is out with an injury but at least we've got plenty of midfield cover. I'd guess the following is likely....
Fox
O'Donnell Muirhead Archibald Sinclair
Paton Murray Bannigan
Lawless Elliot Erskine
Subs: Smith (trialist); Balatoni; Craigen; Halsman; Doolan.
Obviously I think McNamara will continue his policy of keeping a player in the team who did well - also Doolan might not be up for 90 minutes yet but would be a great sub to bring on during the last third of a game when players are tiring a bit.
Not sure about Forbes' match fitness so have left him out of the squad
