However, that first Aviva Premiership fixture, against the Northampton Saints, proved to be his last.
A serious shoulder injury forced him out of the action before the hour mark. Extensive rehab followed, as did surgery, but the popular Bristolian was forced to retire from the game in December.
Director of Rugby Nigel Davies immediately sought to retain Brown's lineout expertise on a short term basis. And, today it was announced that the former England international will now be staying on in a full time capacity.
Brown explained what the new role will consist of:
"It's primarily working on team operations. I'll be helping out in various areas, the lineout being one of them. My strength as a player was in that area and hopefully I can transfer that to some of the guys coming through.
"I'll also be helping to look out for new players, identifying talent and liaising with agents. Looking out for potential new stars.
"Because I got injured so early on in the season, Nigel (Davies) kept me busy and I've been doing aspects of the job every since I got injured.
"So, although I'll be doing a certain amount of what John Brain used to, not too much has fallen between the cracks. It's very much been a continuation of what John used to do."
Having had to retire from playing came as a sudden and unexpected blow, and the 33 year old is full of praise for Gloucester Rugby in the way they've handled the situation.
"I have to stress how delighted I am with the way that Gloucester have approached it. Being injured was a nightmare scenario and something I didn't plan for at all.
"I genuinely thought that I'd play for two, three more years and hopefully finish off my career at Gloucester on my own terms.
"But that didn't happen. And to deal with that was tough. But Gloucester have been massively supportive through all of that, helping me move from player into a future career.
"I'm lucky because I'm still going to be around and still with the team, and so the missing of the rugby side of it isn't quite as prominent as it would it had my time in rugby just come to an abrupt end.
"I still miss playing obviously, especially when you see a game like the one against Saracens at the weekend. It does hurt. You want to be out there playing and wins like Saracens don't come along very often.
"When you have a game like that, in front of a crowd like that at Kingsholm, you obviously miss it. But I'm lucky to still be involved and I'm grateful for that."
And he is especially grateful to Nigel Davies and CEO Stephen Vaughan:
"I've a lot to thank Nigel for, because he and Stephen Vaughan have been the driving forces behind this opportunity for me.
"Nigel wants to develop people in the direction that they want to go in. He's not got a 'my way is the best way' approach. He's very flexible in his approach and has been great for Gloucester this year.
"To have this opportunity is huge, I'm very lucky they're supporting me in this role."
He's already started in his new job as Rugby Operations Manager, but a different and slightly unusual role is in the offing in just a few weeks time.
Gloucester fans are used to seeing him with a number five on his back but, for one night only, he'll be 007 as he appears as James Bond at his Benefit Year Ball at Hartpury College on May 25th.
