Billy Vunipola will make his latest return from injury when Saracens entertain Bristol in the Premiership on Saturday.
England’s number eight broke his arm in the second-Test defeat to South Africa in June – six months after first breaking his arm in Saracens’ European Champions Cup tie with Ospreys.
The 25-year-old has been dogged by a succession of injuries in the past with shoulder and knee problems having kept Vunipola out of England action for more than a year prior to the South African tour.
He was ruled out of the 2015 Rugby World Cup after suffering knee ligament damage against Wales in the pool stages.
A year later, in the autumn of 2016, he missed a chunk of the season following more knee damage, although he was able to return for the end of the 2017 Six Nations and Saracens’ retention of the European Champions Cup.
A long-running shoulder problem forced him out of the British and Irish Lions tour of New Zealand and he had knee surgery last autumn.
He was then ruled out of this year’s Six Nations after breaking his arm for the first time.
