Foley ruled out of Brumbies showdown

Sydney - Waratahs flyhalf Bernard Foley has been ruled out of Saturday's clash with the Brumbies as he is still recovering from a head knock sustained during the pre-season.

The 27-year-old was set to make his first appearance in this year's tournament but was ruled out when he failed to meet concussion protocols after the Waratahs' captain's run in Sydney on Friday.

"Bernard isn't quite 100 percent and still experiencing some symptoms," Waratahs head coach Daryl Gibson told AAP.

"He has trained all week and completed his cognitive tests. We have seen improvements but he still has some symptoms lingering.

"It's frustrating for Bernard being so very close - he more than anyone wants to be back out on the field.

"But we won't want to push him so we'll give him more time and ensure we take all the necessary precautions to get him back to 100 percent."

Bryce Hegarty, who was initially bracketed with Foley will start at flyhalf for the fourth game in a row while David Horwitz will start on the replacements bench.
