Western Force coach Richard Graham has opted for consistency against the Waratahs this Friday, making just one change to his match day 22 as winger Samu Wara is replaced by Cameron Shepherd.

Wara sustained a hamstring injury against the Chiefs last weekend and this forced change sees Rory Sidey move to wing in his place, while Shepherd has been selected on the bench.

The forward pack that has serviced the Force so well this season remains untouched and their battle against a tough Waratahs outfit will again be a pivotal factor in the outcome of this weekend's clash.

The selection headaches that both camps had leading into their original corresponding fixture a month ago is in stark contrast to the settled line-ups being taken into this round eight derby game.

Having already played all of their national rivals away from home, the Force will be hoping to make it two-from-two against their fellow countrymen at Nib Stadium, after disposing of the reigning Super Rugby champion's, the Reds, a fortnight ago.
