Jamie Ritchie has been passed fit and will captain Scotland in their must-win Rugby World Cup Pool B match with the world's number one ranked team Ireland on Saturday.

Ritchie had to sit that game out after taking a knock to the head in their previous match, another hefty win over Tonga.

Among those returning is Blair Kinghorn at fullback, which takes him to the 50-cap milestone.

Winger Darcy Graham retains his place after scoring four tries in the hammering of Romania.

Sione Tuipulotu and Huw Jones resume a familiar starting centre partnership which has enjoyed nine outings in 2023.

As part of a half-back pairing that will combine to pass 140 caps on Saturday, scrumhalf Ali Price gets the nod to partner stand-off Finn Russell.

The Scots have to win to entertain any chance of reaching the last eight -- they are five points adrift of defending champions South Africa and four behind the Irish.

Ireland will start hot favourites as they are on a record run of 16 successive Test victories, including an impressive 13-8 victory over the Springboks in the pool match a fortnight ago.

The Scots, who lost to South Africa in their opening pool game, have been beaten by Ireland in their past eight meetings.
