Brown is likely to play some part of Saturday’s match against St Johnstone after a fortnight of complete rest.
“I just needed a bit of rest,” he revealed. “There was a lot of inflammation between the bones. As soon as that goes away I’ll be feeling a bit younger than I do at the minute. I’ve got to see how it settles.
“The hip could need surgery, but hopefully we don’t need to go that far and everything will settle down.
“I’m feeling a lot better, I’ve had two weeks rest and done nothing at all. I’ve just sat and relaxed.
“I’ll try training on Friday and see how things go. If I can play on Saturday, I will. If not, the bigger game’s Benfica and I’m looking forward to it.”
