Winger Rob Horne and hooker Tatafu Polota-Nau return from injury for the NSW Waratahs’ must-win Super Rugby clash with the Western Force in Perth.

Horne will start on the wing in place of Matt Carraro after recovering from a broken hand, while Polota-Nau will come off the bench in his comeback from a broken arm on Saturday.

Former skipper David Dennis will celebrate his milestone 100th match for his home state after a decade of whole-hearted performances for the Waratahs.

Dennis is one of three changes to the run-on team this week, coming into the second row with Dean Mumm to start on the bench as he battles a knee niggle.

Prop Paddy Ryan replaces injured veteran Benn Robinson, who has been ruled out due to an eye injury suffered in last week’s 26-20 loss to the Brumbies.

The Waratahs travel to Perth on Friday before heading to South Africa ahead of their round-10 match against the Stormers in Cape Town.

Waratahs: Andrew Kellaway, Reece Robinson, Israel Folau, Kurtley Beale, Rob Horne, Bernard Foley, Jed Holloway, Michael Hooper (capt), Jack Dempsey, Will Skelton, David Dennis, Tom Robertson, Hugh Roach, Paddy Ryan. Tatafu Polota-Nau, Jeremy Tilse, Angus Ta’avao, Dean Mumm, Wycliff Palu, Matt Lucas, David Horwitz, Matt Carraro.
