Fiefia is the son of David, the former Weber State football assistant coach who took over the Farmington High program in the summer of 2025.

Fiefia was diagnosed with Ewing’s sarcoma, a rare type of cancer that typically starts growing in the bone, when his family lived in Pocatello, Idaho, while David coached at Idaho State.

Despite the cancer, he battled back from treatments to play 17 football games at receiver and cornerback across his junior and senior seasons. The 2025 graduate totaled 39 receptions for 379 yards and five touchdowns in those two seasons, adding 52 tackles and four interceptions on defense.

“After going through what I went through, all those rounds of chemo, radiation, I just was so thankful for it and like how much I realized how much (football) actually meant to me,” Fiefia told the Standard-Examiner in September 2023.

Afu is the third in a family of seven children.

“His humility and desire to follow the Savior’s example were essential aspects of his nature. As his understanding of his nature and mission grew, so did his ability to influence so many others for good,” Afu’s obituary reads. “At the hardest moments in his life, Afu chose to lift others, whether that meant taking a walk with a child with cancer when he himself was nearly too sick to walk, or comforting his siblings when he had received devastating news of a relapse. He drew abundance to him through the beauty of his open heart.”

“His testimony, strength, love, light and faith has helped us understand the true meaning of unwavering faith in the face of adversity,” David wrote on social media site X.

A celebration of life and viewing program will take place at 6 p.m. Friday, with a viewing at 8 p.m. “This will not be a traditional service as we honor Afu’s Tongan culture and the way we gather as family and community,” his obituary reads.

A viewing will be held from 10-10:30 a.m. Saturday, and a funeral service at 11 a.m.

Those will take place at the Bountiful Regional Center, located at 835 N. 400 East in North Salt Lake City.
