Paul McShane claims he could leave Hull in January because he has been dumped back on the sidelines by Steve Bruce.
McShane was gutted to be axed from Bruce's 18-man squad for Sunday's defeat to Tottenham after starting Hull's previous two games.
Bruce has offered the Republic of Ireland defender a new deal to stay at the KC Stadium, but he is reluctant to stay if he is not playing.
“I can't stick around to be playing games, and playing well, and then be totally left out of a squad, because it is disheartening,” he said.
“I'm not sure what will happen. Probably in January when it all kicks off again, I might know more, but that's the life of a footballer. You don't know where you'll be from one minute to the next.”

McShane, 28, was left out because of Michael Dawson's return and the former Manchester United trainee says it is hard to accept.
“It's a season that’s full of frustration and you can probably understand why,” he said.
"Sunday was a massive disappointment, especially not to be in the squad at all.
“What can you say? I feel as though I'm playing well, probably the best football of my career when I'm playing centre-back.
“It's very tough to take. I'm upbeat now, but it's a killer at the time.
“You have to keep picking yourself up, but how many times can you keep doing it?”
