The new New South Wales Waratahs head coach Michael Cheika has made a change to his coaching structure with Greg Mumm to leave the setup.
32-year-old Mumm joined the Waratahs as coaching co-ordinator at the start of the 2012 season, having previously worked with Sydney University and the Fijian national team.
Cheika says going forward requires some changes.
He says many of the team have had to deal with a level of uncertainty already and he didn't want to prolong it.
