"First and foremost I want to thank each and everyone that prayed and supported me during this new ordeal, you guys are amazing," Haynesworth wrote on Instagram on Thursday. "...Today I started my first dialysis treatments outside the hospital. I’m feeling better than the previous post since the great hospital staff of Williamson Medical pulled more than 12lbs of fluid from in and around my lungs."
He is also seeking a kidney donor, noting that medical expenses will be covered and the person will be compensated.
According to Mike Wilson of the Knoxville News Sentinel, Vanderbilt University Medical Center has received more than 1,000 calls regarding organ donation. A family member is also reportedly "very optimistic" about Haynesworth's outlook.
He has undergone two rounds of dialysis while he awaits a donor match.
Haynesworth posted a picture of himself July 11, writing in the caption his kidneys went into failure four days earlier.
"Some of you may know I've been battling kidney disease for a few years now the time has come family, friends and fans I'm in dire need of a kidney mine have finally failed me on July 7 2019," Haynesworth posted then. "It's hard to believe from being a professional athlete to only 8 season in retirement that my body has taken another major blow. First with the brain aneurism 3 seasons out of the NFL to now my kidneys failing me. But the bright side of this latest ordeal I can ask for help by asking for someone to generously donate a kidney."
Haynesworth explained in 2016 that he "almost died" from the brain aneurysm, although he recovered after an 11-day stay in intensive care at a hospital, per Paul Kuharsky of ESPN.
The 38-year-old spent 10 seasons in the NFL, making two Pro Bowls and earning two All-Pro berths. He spent his first seven seasons with the Tennessee Titans before playing with Washington, the New England Patriots and Tampa Bay Buccaneers.
He last appeared in an NFL game in 2011.
