Mather is the third player to be forced out of the tour by injuryin a week. Mather's injury compounded Scotland's misery which began withSaturday's tour-opening 41-5 drubbing by the Queensland Reds in Brisbane.
Mather joins prop Euan Murray, who failed to play a game becauseof a thigh injury, and fullback Robbie Kydd, who fractured a cheekbone againstthe Reds, who are off home.
Scotland coach Matt Williams called holidaying former Australianunder 21 representative Paul Dearlove into his squad as a replacement, placinghim on to the reserves bench for Wednesday's game against New South WalesCountry in Wollongong. "We needed a replacement for Cammy at short notice and it wasfortuitous that Paul was on holiday in Sydney," Williams said on.
"We made contact with him and he has now joined the squad forthe NSW Country game."
"I'll certainly do my very best to make the most of thisopportunity. The chance to pull on the jersey and represent Scotlandreally means so much to me and it's one I'll certainly not take lightly.
"Hopefully I'll be able to get on in the game and get thechance to show what I can do on the pitch."
