Duo miss out for Inverness

The midfield pair were both sent off as Caley Thistle were thumped 5-0 by Dundee United in last year's competition and will now sit out Saturday's fourth-round clash in Paisley as their bans finally kick in.

Captain Richie Foran remains unavailable with a knee injury.

Provisional squad: Brill, Raven, Shinnie, Warren, Meekings, Tremarco, Draper, Ross, Vincent, Doran, McKay, Polworth, Baptie, Williams, Horner, Evans, Devine, Sekajja, Esson.
