The City skipper is not quite ready to return to action against his former club.

'I won't be ready for Sunday," Purse told the Echo.

'I would love to play and I am almost ready, but I also have to be truthful and I know in my heart the manager cannot make a change after the guys played so well in the 4-1 home win against Preston.

'I have been out for five weeks and I'm short of match fitness, but if I'm needed for the substitutes bench I'd jump at the chance.'

A large crowd is expected at St Andrews with the home side doing a "kids for a quid" offer as well as allowing ST holders to purchase additional tickets for a fiver a time.
