Updated June 18 at 7 a.m.: Entertainment Weekly reports that Ron Lester died around 9 p.m. last night of liver and kidney failure. He is reportedly survived by his fiancee, Jennifer Worland.

Original story: Ron Lester, who memorably portrayed Billy Bob in the hit 1999 Texas football movie Varsity Blues, is listed in "critical condition" at an unnamed Dallas hospital, TMZ reports.

Updated at 6:37 p.m.: Entertainment Weekly reports that, according to his agent Dave Bradley, Lester has had his breathing tubes removed and has been moved from the ICU to hospice care.

The 45-year-old actor, who is originally from Georgia, moved to Dallas in 2013. He was reportedly hospitalized in November due to issues with his liver and kidneys, and he told the website in January he also has a heart condition. According to unnamed sources, Lester has been in the Dallas hospital for four months, and his condition has deteriorated.

In addition to movie roles in Not Another Teen Movie and Good Burger, and a recurring role on the beloved television show Freaks and Geeks, Lester is known for having lost almost 350 lbs. following gastric bypass surgery in 2001. He has since spoken candidly about the "dangerous" surgery -- he reportedly flat-lined during the initial procedure -- and his ambivalence toward its effect on his career and personal life.
