The 33-year-old will accept a reduction in salary to sign fresh terms but is anxious for some direction from the club.
"I'll stay here if they offer me a contract but they're leaving it a bit late," said Walker.
"It would be nice if they offered something that I could say yes or no to.
"I was worried about it because I've been out for so long with the injury.
"But the club have got to come to us at some stage but it is getting nearer the end of the season.
"There's no point in getting worried about my situation because I'm just happy to be back playing."
