Hull veteran Dean Windass says boss Phil Brown has not spoken to him since before Christmas.
The 39-year-old striker has been left out of the squad for the last two games after being substituted at half-time during Hull's 5-1 thrashing at Manchester City on Boxing Day.
Windass has endured a frustrating time since scoring the winner for his hometown club in last season's Championship play-off final, making just five Premier League appearances.
He had hoped to feature in last weekend's FA Cup third-round clash against Newcastle, for which Brown made seven changes, but did not even make the bench.
Windass wrote in his blog on www.itv.com: "Our boss made a number of changes to the side and gave some fringe players a chance to impress, but sadly I wasn't one of them.
"It's fair to say I'm getting very frustrated and I have no idea what is happening with my situation as the manager hasn't spoken to me for three weeks.
"I'm not saying that to try to grab a headline - he's got other priorities like trying to run a football club - but simply to show how uncertain things are for me."
Windass has been linked with Leeds, Grimsby and Hartlepool this season but claims to know of no interest in the current transfer window.
His contract at the KC Stadium ends in the summer but he insists he will continue to work hard for Hull and take his chance when it comes.
He added: "As ever I'm training hard, biting my lip and getting on with things. I've said it so many times over the season but I just have to be ready if I'm called upon.
"I know Hull have already been linked with a number of strikers in the transfer window which would obviously put my future here further in doubt, but I've heard nothing from the club or my agents about anyone making an offer for me."
