Sean O’Brien: I’ll quit rugby if my hamstring tears again

The flanker suffered a serious tear to the muscle during Ireland’s Six Nations game against France in Paris last February and subsequently underwent surgery in early summer after an initial attempt at rehab failed.
The good news is that his recovery is on track and maybe even a week or two further down the line than anticipated at this point. Back running with the squad this week and next, he should be in contact the week after that.
