The £800,000 signing has not featured in a Premiership game this season and Sir Bobby told the press at the weekend that he could leave the club if he wants to.
"I'm not stupid, I know that I've not got a future here," Quinn told The Journal.
"I've not played for the first team for almost two season now. I've been frozen out and that is obviously disappointing, but it is one of those things.
"I read the manager's comments in the paper and although he hasn't really said anything to me about it I already realised the situation.
"I want to be playing regularly again and that is what I'm trying to achieve. Hopefully something will be sorted out in the summer. I'd like to stay in the Premiership because I think I'm good enough to do that, but we'll have to see what clubs come in for me."
Quinn enjoyed a successful loan spell at former club Sheffield United earlier in the season and Blades boss Neil Warnock indicated that he would be keen to make the move permanent if they can win promotion via the play-offs.
