Munster and Leinster have named strong teams boasting plenty of Ireland players for their United Rugby Championship matches against South African opposition on Saturday.

Munster have named Calvin Nash, Jack Crowley, Craig Casey and Tadhg Beirne to start against the Sharks in Durban (15:00 BST), while Leinster have included a host of their Test players for their top-of-the-table clash with the Lions at Aviva Stadium (17:15).

Munster boss Graham Rowntree makes four changes from last week's loss to the Stormers with Rory Scannell, Casey, Stephen Archer and John Hodnett all recalled.

Caelan Doris, who was this week named Ireland captain for next month's autumn internationals, skippers a Leinster side featuring Robbie Henshaw for the first time this season. Henshaw will be partnered in midfield by Hugh Cooney, who makes his first senior start.

With Ciaran Frawley not included after his injury against Connacht last weekend, Sam Prendergast - who was included in the Ireland squad this week - starts at fly-half for Leo Cullen's side.
