The Republic of Ireland international, who had a transfer request rejected, is believed to have been the subject of several bids from Aston Villa last month.
However, Hoolahan was denied a move and has been included in the squad for Saturday's home match against Manchester City.
"Wes will be in the squad," Sky Sports News quotes Hughton as saying. "There is only one thing that is certain now - Wes will be here.
"Wes is very committed. We have a 14-game end-of-season run-in and he's very much there for the challenge, very much part of the squad. He's very motivated.
"He's knuckled down very well in training. He is a good player as we are all aware of and he will be fighting the same as everyone else for a place."
The Canaries are currently 15th in the Premier League table.
