Australian Head coach Ewen McKenzie has named Ben Mowen as Wallabies captain for this weekend's Test match against England at Twickenham.
Mowen captained the Wallabies in their 14-13 victory over Argentina during the Rugby Championship and will lead the side out again I the opening QbE Autumn international.
Quade Cooper has been selected as vice-captain by head coach Ewen McKenzie, who has urged Horwill to rediscover his
"There's no doubting James is a world-class leader but it's important he is putting his own personal performance first and playing to the level we know he is capable of on a weekly basis," said McKenzie.
"By his own lofty standards, James would admit he hasn't been at peak form," McKenzie told Sky Sport.
"So, we've made the decision to this week remove the added pressures and responsibilities of being a captain so that he can focus entirely on bringing his 'A' game.
"Decisions like these are never easy, but sometimes you need to make hard choices for the long-term benefit of the individual. A strong individual performance will be the best contribution he can make to this game.
"Without the captaincy, Ben now gets another opportunity to lead his country, while we're recognising Quade for the ongoing decision-making role he plays on the field and the positive involvements he continues to make in contributing to the culture of the team off the field.
"However, like we do every week, we'll re-assess all selection decisions for next week's game against Italy after we focus on taking care of business against England on Saturday."
