Montpellier - Montpellier's South African playmaker Johan Goosen will be out of action for "at least two months" with a badly twisted ankle, the club announced Tuesday.

Goosen sustained the injury early in Sunday's match against Toulon, which Montpellier won 29-17 to consolidate their fourth place in the Top 14.

The Springbok's absence adds to coach Vern Cotter's woes ahead of their European Champions Cup match with Edinburgh on Saturday, with ex-All Black flyhalf Aaron Cruden (calf) out and Frans Steyn nursing a biceps injury.

Winger Timoci Nagusa suffered a thigh injury in the Toulon match, with fellow Fijian Nemani Nadolo and scrumhalf Benoit Paillaugue also both out. Georgian prop Levan Chilachava, locks Jacques Du Plessis and Konstantine Mikautadze, and backrowers Julien Bardy and Yacouba Camara, are all also sidelined.

Toulon, sitting a lowly 12th in the Top 14, have drafted in Kiwi lock Brian Alainu'uese from Glasgow on a one-year deal with one more as an option.

He is the first of five recruits to be unveiled by Toulon president Mourad Boudjellal to boost a pack lacking the injured Corentin Vernet, Juandre Kruger, Florian Fresia, Facundo Isa and Charles Ollivon.
