"The op went well and there have been no complications," he said, after returning to Wasps training ground this week to begin his rehab training. "I 'm very much looking forward to getting started on my rehab, which begins this week. I've got around eight weeks before I'm back playing, and that gives me the opportunity to complete a full pre-season programme, which I have found in the past to be massively beneficial as the season gets longer and longer.
"So in a way the injury is a blessing in disguise, as it gives me a bit more time to recover and come back fully fit and fresh after a long summer of international rugby.
"The medical team are predicting it will be eight weeks from the operation until I can play again, so I'm hoping to be back playing in time for the start of Wasps European campaign and be available for selection for the Autumn Internationals."
