It was actually a cruciate ligament injury - sustained against Newport Gwent Dragons in November 2013 - that originally side-lined Sherry.
But the front-row is determined to make his mark in the GUINNESS PRO12 this season.
"I was on my own for long enough so it's great to be back with the squad, and not be on my own," he told the Munster website.
"Pre-season is tough, some days it is horrendous, but it's nothing in comparison to sitting around and wondering what you are going to do with your life at 25, 26, if rugby was to be taken away. In that context, getting through a tough pre-season session is not that much of a big deal.
"I did think the shoulder would be career-threatening at times, especially when I was told where it needed to be at certain stages and it was nowhere near that.
"I knew myself, I was going for very basic rehab sessions and grimacing in agony, trying to convince myself it was ok. I'd stay up all night moving my shoulder around, trying to see what was comfortable and nothing was.
"I was motivated throughout but some days it was hard going, thinking I was fighting a losing battle."
