NEW YORK — The fan mail flooded Jordan Clarkson’s inbox. That left the Lakers’ second-year guard endlessly sifting through them.

But as Clarkson remained consumed with his offseason training, one letter caught his eye.

Jeffrey Yourman, a 22-year-old student at Kean University in Union, N.J., informed Clarkson he has received lifelong treatment for cystic fibrosis, a genetic lung disorder that also affects his organs, sinuses, kidneys and liver. On top of that, Yourman’s 22-year-old girlfriend, Roni Bibring, is in remission from leukemia and partially paralyzed.

“It is our strength and stamina that keeps us both going and dealing with our disabilities together,” Yourman wrote through lettrs.com, a digital fan app that recently partnered with Clarkson. “I would love to have a conversation with you when you aren’t busy with this extremely hectic NBA season.”

Clarkson will make Yourman’s wish come true. Clarkson is giving Yourman and Bibring two tickets for when the Lakers (0-4) visit the Brooklyn Nets (0-4) on Friday at Barclays Center. Afterward, Clarkson will have a meet-and-greet with the couple and share his own story. Clarkson’s father, Mike, was diagnosed in 2014 with a rare form of cancer in his lower back, something he has since overcome.

“It’s tough when I saw what my dad went through,” Jordan Clarkson said in an interview with Los Angeles News Group. “I hope this brings some joy to them. Hopefully we can get some more wins and make him happier.”

Jordan Clarkson has represented the Lakers’ rare bright spot, averaging a team-leading 18.3 points on 56.4 percent shooting through four games. He also posted a career-high 30 points in Tuesday’s loss to Denver.

Friday means so much more to Yourman.

“It’s a complete shock and it’s very exciting,” said Yourman, who is majoring in public administration at Kean University and plans to apply to various schools for post-graduate studies in computer science. “It’s not just about meeting Jordan Clarkson. If you have good family and friend support, that’s what gets you through things.”

While there is currently no cure for Yourman’s disease, he has stayed healthy with daily antibiotics and exercise, including pickup basketball. Bibring has received chemotherapy for the past three years.

Meanwhile, Mike Clarkson had two surgeries to remove a tumor wrapped around his spine that threatened to spread to his lungs. After spending most of 2014 rehabbing while confined to a wheelchair, Mike Clarkson can walk and has since resumed working in San Antonio with the Air Force.

“He’s doing well,” Jordan Clarkson said of his father. “I always told him to keep his head up and I would do everything I can to keep him going and proud.”

Through lettrs.com, Clarkson’s following has seen a boost in the Philippines. Clarkson’s biological mother, Annette Davis, is Filipino.

“It definitely leaves a lasting impression,” Jordan Clarkson said. “Sometimes it is a lot to read. But I feel like it helps me be more connected to people.”

Jordan Clarkson and Yourman anticipate that connection will strengthen once they meet Friday. Yourman sounded optimistic he can also convince Bibring to convert from a Nets to a Lakers fan and wear Clarkson’s jersey.

“I hope she’ll be cheering for the Lakers,” Yourman said. “It won’t be a fun day if the Lakers lose. It’ll be even worse if she brags about it to me.”

Or perhaps meeting Jordan Clarkson will be good enough, a digital letter soon forging into what Clarkson and Yourman hope morphs into a long-lasting friendship.
