Now that he is back in the world title mix, he is determined to win the IBF belt to redeem himself.
"I think, as far as I'm concerned, I haven't lost at all in the last three years," Malignaggi told BoxNation.
"Adrien Broner was given my world title, so I feel like I need to win another world title to kind of rightfully get what's mine. My name just became a filler on [Broner's] resume and I feel like for that reason I need to get a world title to kind of redeem myself.
"I mean Shawn worked hard for this, but it's a world championship that I want and now I got the chance to do it."
Malignaggi faces Porter on Saturday night, with the winner likely to fight British star Kell Brook.
