Houston answers Wallabies call

The Wallabies have re-called Leroy Houston to the squad to replace injured Sean McMahon for the final round of The Rugby Championship against Argentina at Twickenham.

McMahon has been ruled out for up to a month following an ankle injury sustained in the Wallabies 18-10 loss to the Springboks in Pretoria.

Wallabies number 8 David Pocock is also on the sidelines due to injury, with Houston and Wallabies rookie Lopeti Timani both in contention for selection this weekend's clash.
