England Rugby have confirmed that Mako Vunipola will undergo surgery for a hamstring injury sustained during Saracens Heineken Champions Cup final win over Leinster last weekend.
The Saracens prop has been ruled out for three months meaning he will miss the remainder of the Premiership season.
It is thought that Vunipola will be fit for England’s World Cup campaign in Japan.
However, he will be under pressure to return for the warm-up fixtures when Eddie Jones’ side face Wales on 11 and 17 August, before playing Ireland on 24 August and Italy the following week on 6 September.
Meanwhile, Saracens have also confirmed that USA prop Titi Lamositele picked up an ankle injury during the 20-10 win. However, the injury isn’t thought to be too serious but sidelines him for Sarries’ remaining fixtures.
