Club captain Jody Craddock admits fearing for his future as he attempts to win another Wolves deal.
The 35-year-old centre-back, who has missed most of the season with a serious hip and thigh injury, will be out of contract in the summer.
But, having made only one appearance since October, fit again Craddock is running out of time to prove he deserves to stay at Molineux for another season.
After being named on the bench for Wolves' FA Cup fourth round tie with Stoke, the former Sunderland man is hoping for another opportunity to impress boss Mick McCarthy.
He said: "I know I have to get back into the team to play for a new contract. It pushes me that little bit more to perform.
"The fact is I have not got long left in my career and right now I have to take every opportunity that comes my way.
"My contract is up in the summer. For the last five years I have only been offered one year contracts. Yes it's frustrating but I have learned to accept it.
"Last year was a big one for me because I was coming up to my pensionable age. In some ways this season is a bonus.
"But it's still an anxious time not knowing the outcome of my career.
"It would be great though if I could help Wolves stay up and maybe get to Wembley too."
Long serving Craddock, who has made over 200 appearances for the club, insists he is still physically fit enough to carry on.
He added: "As soon as you get past 33 and get an injury, everyone says you must have slowed down and asks whether you can still do it.
"If I have lost some pace I think I can make up for it with my experience."
