Sunwolves

The 24-year-old has not played for the Wallabies since their heavy loss at the hands of Scotland on last year's Spring Tour, after which he joined Suntory in the Top League.

With Japan hosting the 2019 Rugby World Cup, however, the surrounding Top League seasons were drastically shortened - leaving a window for Australian players to return home for a Super Rugby season and a potential World Cup tilt.

The Reds, Rebels and even the Force approached McMahon but RUGBY.com.au can reveal he turned his back on all offers to sign for the Sunwolves for the 2019 Super Rugby season.

Ben Alexander and Allan Alaalatoa will team up in the front row for their match against the Sunwolves, with Sio nursing a 'minor niggle' back in Canberra.

Richie Arnold has usurped his twin Rory for his debut Brumbies start, with the latter on the pine in Tokyo.

Canberra Vikings captain and 2016 Olympian Tom Cusack will have the first chance to take the seven jersey as David Pocock recovers from knee surgery, with Lochie McCaffrey on the bench.

Cusack will combine with Rob Valetini and breakout 2017 star Isi Naisarani in the backrow in the opening clash.

The final result was never in doubt, although the Highlanders looked rusty coming off the bye and weren't always convincing, particularly in the first half.

Their scrum was generally efficient and the set piece solid despite the absence of All Blacks flanker Elliot Dixon, ruled out late by a knee infection.

It took just four minutes for the Highlanders to punish the Sunwolves' slow start, the visitors' poor handling gifting plenty of early possession.

The dynamic 12-test All Blacks winger, along with first-five-eighth Lima Sopoaga, were both injured against the Blues at Eden Park in Super Rugby round three on March 11.

Fast forward more than a month and Naholo is back in training after recovering from his hamstring injury and is in contention to be named later this week to take the field for the Highlanders after playing 40 minutes of club rugby in Taranaki for Spotswood United.

Sopoaga is still doing his recovery and performance programme and is likely to be considered for selection in two weeks.
