Brady was playing through the pain barrier in the early part of the season, scoring four times in the process, but could no longer go on and was sent for a hernia operation after netting the winner against West Ham on 1-0 on September 28.
"Robbie has trained this week which just goes to show what the medical people can do. It's just over two weeks since the operation," said Bruce.
"We'll see for a reaction but as long as there isn't one he'll come straight back in the squad. It's quite remarkable what they can do to fix what is labelled as a hernia.
"To be playing in two and a half weeks shows what they can do.
"He's pain free and running around like a two-year-old so let's hope he stays like that."
