Newcastle United keeper Steve Harper is willing to play through the pain barrier to retain the club's number one jersey.
Harper has been handed a chance under Glenn Roeder after first-choice Shay Given was injured in their win at West Ham.
The 31-year-old has been waiting in the Magpies' wings for some time and has no thoughts of missing out now, despite carrying a groin injury.
It had been thought Harper might step aside to let Pavel Srnicek feature against Middlesbrough on Sunday, but he is not looking to sit out the Tyne-Tees derby.
"I have waited five years for my chance and I am not giving it all up without a fight," said Harper.
"You will have to knock me out to stop me playing at Middlesbrough on Sunday.
"Don't forget, I have learned from old Lazarus himself, Shay Given, about coming back from the dead and taking his place in the Newcastle goal.
"I hurt my groin at Old Trafford a couple of weeks ago and I have not trained since last weekend.
"It has been niggling away and I wanted to train before the match. But I was instructed not to by the medical team, who said I would struggle to play two games in three days.
"But I was adamant I was okay to play and I kept badgering enough people and in the end, managed to get the shout."
