Moreau, who was a free agent, had the diagnosis revealed while undergoing a medical examination with the Saints during an offseason visit with his hometown organization.
The 25-year-old shared an emotional message on Twitter, revealing the diagnosis to his fans and explaining his next steps.
“Through somewhat of a miraculous process, this Free Agency period has been life changing for me. During a routine physical conducted by the Saint’s medical team down in New Orleans, I’ve come to learn that I have Hodgkin’s Lymphoma, and will be stepping away from football at this time to fight a new opponent: Cancer. I’m grateful for the support and thankful for people who have stood firm with me. There hasn’t been a single step I’ve taken without hundreds of people lighting the path before me, and I will continue to seek their guidance. That being said, I’ll go kick this thing’s ass and get back to doing what I love! AMDG!” Moreau wrote on Twitter.
Moreau was a fourth-round pick by the Raiders in the 2019 NFL draft, having been selected 137th overall out of LSU. He played four seasons for the Tigers from 2015-18, making 30 appearances and catching six touchdown passes.
The tight end has featured in 61 games in his pro career, making 34 starts. In 2022, he recorded a career-high 33 receptions for 420 yards, scoring two touchdowns for Las Vegas.
