The Peko family is in the midst of two fights.

Kyle's trying to make the Bills, while his wife Giuliana ​fights for her life after being diagnosed with Stage III Hodgkin lymphoma.

"It's pretty unreal. Kind of devastating, but my wife is strong, she's a fighter. I know she's taken it harder than me, obviously. She's the one with the diagnosis. I just have to be strong for her and our kids when she can't be. I have to be the rock for our family as much as I can be while she's back there,” said Kyle Peko.

Peko reported to training camp Friday after an excused absence from Day One — a decision made by his wife of five years.

"This is how I support my family. This is the way I take care of her and my kids. To be honest, she's the one who told me to get back out here. She told me not to miss. As a husband and as a man it's my obligation to be there with my family and you're right, it's crazy that I'm here, but it's her. She wouldn't want it any other way,” he said.

The Bills preach family first, and as Peko’s family deals with this challenge, his one at St. John Fisher College is helping as best they can.

"Of course I kind of kept it private for a little bit. It's kind of a big deal. It was kind of hard for me to accept or talk about it. As soon as I did and as soon as I sent a text to the D-line group and the coaches, they reached out and said any way that they can help, anything. Everyone's been super supportive. Prayers, good vibes, everything. Positive energy. That's what we've received,” said Peko.

"​Letting him know that we're there for him. Supporting him every way that we can. I think it's just very admirable that Kyle's here, so letting him know that. I think it's good him to be around his teammates and they've certainly reached out to him, in particular last night when he let everyone know what they're going through as a family," said head coach Sean McDermott.

General manager Brandon Beane and owner Terry Pegula were also among those showing their support for Peko upon his arrival at camp. It's something that McDermott feels puts things into perspective for his team: that football is second to life.
