Mather last played for Scotland in 2000

Glasgow flanker Cameron Mather has been called into the Scotland World Cup squad as a replacement for the injured Andrew Mower.

The 31-year-old New Zealand-born forward won the last of his four caps as a replacement against France during the 2000 Six Nations campaign.

Mather will fly out to Australia on Thursday evening and is unlikely to be involved in Scotland's second Pool B outing against the United States in Brisbane on Monday.

With specialist openside Donnie Macfadyen deemed not fit enough to travel, head coach Ian McGeechan plumped for Mather over Andrew Dall and Allister Hogg after some fine recent performances for Glasgow this season.

"Cammie is in fine form and we've been monitoring him closely," said McGeechan.

"If required, he can also play at the other side of the scrum, which is one of the criteria we used when making our decision.

"Donnie Macfadyen was very much in our thoughts but after consultation with the Glasgow doctor and physiotherapist it was felt Donnie was not going to be fit to travel because of a shoulder injury. We feel Cammie meets our requirements."

Mower sustained a serious knee injury during a training session on Wednesday.

The 28-year-old, who won his 13th cap in the recent warm-up Test against Wales, pulled up during training and was taken to hospital in Brisbane.

A scan showed that he had damaged the medial meniscus and that he would also require anterior cruciate ligament reconstruction.

Scotland manager Dougie Morgan said: "We're all saddened that Andrew's World Cup has ended in this manner.

"The injury is unrelated to the knee knock which prevented him from being involved in the match against Japan last weekend."

Mather told the SRU website: "Obviously my heart goes out to Andrew. Playing rugby for as long as I have you know what it means when you miss out on an opportunity to play in the World Cup."

"I decided to throw in my lot with Glasgow and I knew that if I could get myself playing well week in, week out for Glasgow then other things could happen."
