Wales centre George North has undergone surgery after suffering a cheekbone injury.
North was hurt during Ospreys’ Heineken Champions Cup defeat against Leicester last weekend, going off at half-time.
But Ospreys boss Toby Booth has delivered an encouraging fitness bulletin, claiming that North “will be good within a two to three-week period”.
North, who has won 109 caps and started all four of Wales’ Autumn Nations Series Tests last month, is set to be an integral part of Gatland’s plans.
Booth said that North had an operation on Wednesday, adding: “It a cheekbone and he’s okay. All has gone well.
“I have seen him this week and he has got a nice shiny black eye.
“Outside of that, he’s quite buoyant, so that probably speaks volumes about how he feels.”
North will miss Ospreys’ Champions Cup appointment with Montpellier on Saturday, and also looks set to sit out United Rugby Championship festive derbies against the Scarlets and Cardiff.
