Hobbs, a 25-year-old centre-back, is currently on a season-long loan at the City Ground and had agreed a pre-contract with Forest when his deal with the Tigers expires in the summer.
However, Latics seem prepared to hijack that deal with a cash offer which would be preferential to Hull compared to seeing him depart at the end of his contract.
That could force Forest to enter a January bidding war for a player they thought was due to join them in a few months' time on a free.
"I'm sure something will happen there," Bruce said to BBC Radio Humberside after seeing his team progress to the fourth round of the FA Cup.
"We have had a firm enquiry from Wigan concerning Hobbs - that's on the agenda.
"There's one or two others sniffing around, I've had one or two phone calls regarding Jack. We'll obviously see what he wants to do and see what happens in the next few weeks with that."
Bruce admits the chance to get money for the ex-Liverpool trainee is obviously a high priority for him.
He added: "My job's to look after this football club as best I can- that's part of my job."
