The long-serving goalkeeper handed in a transfer request last Friday - accepted by the club - but in typical, ironic football fashion, came in from the cold when Neil Sullivan was sent off at Brentford on Tuesday.
New first-choice keeper Sullivan will have to serve a one-match ban and will miss the Premiership trip to Coventry City on October 14.
Walker said: "It doesn't really change my position. I presume Sully will play the next few games until his ban comes in. I think that will be Coventry away and it will be great to play in that game.
"Obviously I was disappointed at the start of the season and it was just nice to get out there in a proper game and just play a match. It feels like a long time since I did that - it seems like it anyway.
"We can only wait to see what happens now. I've always said that I just want to play. At the moment I'm not playing regularly and I need to be.
"It was nice just to get out there and now I should have another game coming up. At least that's something to look forward to. When you work so hard in training you always need something at the end of it."
Ian Walker is back in the first-team frame again - but insists his position at the Lane has not changed.
