The Western Force rugby coach John Mitchell will assist the Golden Lions in South Africa's Currie Cup competition later this year.
Coach Dick Muir will be with the Springboks during the Tri-Nations in his capacity as backline coach, and will return to the Lions during the final four to six weeks of the Currie Cup.
During his absence, Mitchell will head the coaching team and will work closely with Muir during the final weeks of the competition.
Working with Mitchell will be Johan Ackermann, who will continue as the team's forwards coach, while Carlos Spencer will take on a coaching role as backline players coach.
Mitchell, who is contracted to the Western Force until the end of the 2011 Super 15 competition, will return to Perth at the end of the Currie Cup competition to prepare the Australian franchise for the 2011 competition.
