The 39-year-old has acted as understudy to Allan McGregor this season and has made three Premier League appearances this season.
And while the former Newcastle United shot-stopper admits he could easily continue playing, he is leaving his options open for now.
"I'm 40 in March and while I don't feel it I realise nothing lasts for life," he said in the Newcastle Chronicle.
"I'm really open-minded about what I do next.
"Right now, my one concern is to get back on the field and play as many matches as I can for Hull. I made 19 appearances last season when Hull enjoyed their best top flight campaign ever, and want to add to my overall total of 23.
"I was injured against Arsenal at the Emirates. I was playing well too – you're always busy down there – and we were drawing 1-1 when I got hurt.
"I hate being injured and at my age I can't afford to be, so I rushed back, played against Burnley, and aggravated my bicep and shoulder again. But I'll return very shortly and then there is half a season still to go."
