It's make or break for both Paul Malignaggi and Zab Judah when they clash at the Barclays Center in New York on Saturday night.
The former world champions, now in the veteran stage, meet in a non-title fight with pair knowing that defeat could spell the end of their careers.
For Malignaggi, who is coming into the fight on the back of a defeat to Adrien Broner, a sixth career loss would leave him with little bargaining power.
"I expect the best Zab Judah, a Zab Judah who is going to be fighting for his boxing career," he said. "I feel the same way.
"If we saw each other in the gym, we would try to knock each other out. There's no love taps. With this much on the line you can bet we're both going to have it out on Saturday.
"You have to be stubborn to have longevity. One or two losses can quickly demote you to a second level fighter, but you have to have the stubbornness to keep going.
"There's a lot of emotion, but at the end of the day we gotta do what we gotta do to win.
"It's exciting every time you're part of a big promotion, it's not a world championship fight, but it still has that feel and that vibe. On Saturday night it will feel like it's a championship fight in Barclays Center."
The fight provides support on a show that contains three world title contests, headed by Devon Alexander's latest IBF welterweight title defence against Shawn Porter.
Sakio Bika defends his WBC super-middleweight title against Anthony Dirrell while Erislandy Lara and Austin Trout battle for the vacant WBA light-middleweight title.
