Brumbies back-rower Jarrad Butler is expecting the under-threat Melbourne Rebels to be desperate to prove a point in Saturday’s Super Rugby showdown.

The ARU on Tuesday revised its initial timeline to decide if it will be the Rebels or the Western Force which are chopped from Super Rugby in 2018, meaning Melbourne will face the Brumbies at AAMI Park with the axe hanging over their heads.

“They’ll be motivated to win regardless but I’m sure they’ll want to prove some people wrong,” Butler said on Tuesday.
