Greg Halford believes his Pompey future hinges on his red-card appeal.
The on-loan Wolves ace was able to play against Hull yesterday after the club officially disputed his Watford sending off for violent conduct, therefore delaying any potential ban.
Halford responded with a goal and another good performance in the 3-2 defeat at Fratton Park.
The 26-year-old's original loan is now up and he was scheduled to return to Wolves today.
However, Pompey boss Steve Cotterill wants him back and Mick McCarthy has agreed to send him out on loan again to the Blues.
Quite when Halford returns, though, will depend on whether the ban is upheld, with his scheduled three-match suspension being upped to four games should he fail.
In the meantime, Halford remains uncertain where and when he will be playing his football next.
He said: 'On Sunday, we were contemplating whether to appeal or not. If we didn't, I could get all three games out of the way within a week.
'My loan finished after yesterday's game, Wolves have a game tomorrow and it is the FA Cup on Saturday.
'But I think the manager wanted to have as strong a side as possible yesterday and an appeal was worthy.
'There has been a lot of talk about receiving a contract here but it all depends on whether this appeal goes through or not.
'There is no point coming back for the four games I could be suspended for, so I might as well just stay up in Birmingham and train with Wolves.
'After that, I couldn't tell you. I just want to play football and if it means coming down here I'll do that.'
