Connor McCaffery’s brother Jack McCaffery is stepping away from basketball following a recent cancer diagnosis.

Jack, 20, a forward on the University of Richmond Spiders men’s basketball team, will take an “indefinite medical leave” after being diagnosed with Hodgkin’s lymphoma, the team announced on Sunday, Nov. 8.

Hodgkin’s lymphoma is a cancer of the lymphatic system, which acts as the body’s drainage, filtering, and defense system, according to Mayo Clinic.

After being evaluated by Richmond’s medical staff last week, Jack traveled home with his parents and was admitted to the Hospital of the University of Pennsylvania, where he has begun cancer treatment, the team said.

Richmond Men’s Basketball Coach Chris Mooney in a statement that Jack was an “important part of our program” and a “tremendous teammate who has earned the respect of everyone around him through his hard work, character and commitment to doing things the right way, both on the court and in the classroom.” 

“Our entire program will be there for him and his family every step of the way on his path to recovery,” he added.

Dr. Alison Wakoff Loren of Penn Medicine said in a statement that the medical team is “confident in Jack’s treatment plan and Penn Medicine’s team of lymphoma experts.” She noted that while Hodgkin’s lymphoma “mainly affects young people in their 20s,” it is “a highly curable form of cancer.” The team’s goal, she added, is to help Jack complete treatment safely and return to school and basketball “as soon as we can.”

Jack’s family also has also shared their support for him as he takes time away from basketball to recover. Connor, who is dating WNBA star Caitlin Clark, shared an Instagram carousel on Sunday, Nov. 8 with photos of himself and his little brother.

He wrote, “Nobody stronger than u to fight this 🙏🏼❤️ you’ve got us all with you and we love you ❤️ CANCER SUCKS!!!!!!!!”

Jack and Connor’s father Fran McCaffery, who coaches the men’s basketball team at the University of Pennsylvania, also shared a statement saying, “We are grateful to the Richmond coaching staff and medical team for their prompt response, and to Kevin Mahoney and the doctors and nurses here at the Hospital of the University of Pennsylvania.”

He continued, “He is in great hands and our family feels blessed to be here, where Jack’s care is directed by this world-class care team.”
