The 2nd Aussie derby for the weekend will have most of SA glued to their screens to see if the Reds can rumble the Waratahs and keep the Stormers and Sharks in the hunt for a home semi.
Waratahs coach Ewan McKenzie has declined naming a starting Xv and will do so shortly before kick-off.
Will the Waratahs book their home Semi?
Or will the Reds keep the SA hopes alive?
Kick-off in Brisbane at 11:40 SA time.
