Rest and rehabilitation since then have not progressed the situation as quickly as player and club would have liked, so Alex underwent surgery over the weekend.
Talking to the local media this week, Director of Rugby Nigel Davies provided an update:
"It's not good news. Alex has got nerve damage in his shoulder and, as a result of that, will be out for at least the rest of the season.
"We tried to avoid it, but the op was necessary in the end because the symptoms weren't moving. When the surgeons got in there, they realised that there was a lot of damage and had to do a lot of repair work.
"So, it's bad news for Alex and not the best of news for us. We obviously wish Alex all the best and we're right behind him. We'll see how things progress over the next couple of months."
In the meantime, Davies confirmed that the club will still be keeping Brown involved and utilising extensive lineout knowledge.
"He'll certainly be helping in terms of his knowledge on lineouts, which he has been doing already since he picked up the injury.
"That's very beneficial to us. He's pitchside looking at what the opposition are doing, defensively and on their own ball, and provides feedback on that.
"He'll still be a big part of Gloucester Rugby, and contributing to the cause, even though he won't be able to play for the rest of the season."
