Celtic have failed in a bid to sign Wolves striker Leigh Griffiths.
A post on Wolves' official Twitter account read: "Kenny has confirmed that Celtic have made a bid for Leigh Griffiths which has been rejected. Striker remains in squad for Oldham game."
Griffiths has scored 13 goals for Wolves this season but he has only started two of the last seven matches, since Jackett criticised his work-rate after taking him off at half-time in a defeat by MK Dons.
Griffiths last week stated it would be an "honour" to play for Celtic and admitted he wanted more certainty about his future at Wolves.
The former Livingston and Dundee striker scored 28 goals for Hibernian in his second loan spell with his boyhood heroes over the last two seasons.
The 23-year-old signed a new two-year contract at Molineux in August, with the option of another 12 months.
Jackett would not rule out selling Griffiths if a higher bid came in.
The Wolves boss, quoted on his club's Facebook page, said: "We've had a bid from Celtic which has been formalised but the club have turned it down.
"We do understand every player has their price but we are not desperate to sell players here.
"Leigh has gone public to say he is interested in the Celtic situation as most Scottish lads would be when a club of that size come in.
"But the deal would have to be right for us and we will have to see how it goes. If not Leigh is still part of our squad and is with us for Oldham tomorrow and Bradford on Saturday."
