Matt Lauer will replace the sportscaster in tonight's primetime Olympics coverage after his eye infection spread, NBC announced.
Costas's eye infection has been a lingering talking point throughout the Sochi Olympics, ever since he took the air Thursday wearing glasses, his left eye reddened and watery.
After the infection spread, he turned to vodka -- downing booze alongside fellow on-air personality Mary Carillo on last night's episode of "Olympic Late Night."
Costas joked about his pinkeye before drinking the liquor.
"My eyes can't get any redder, no matter what I do," he said.
"I'll drink to that," Carillo responded, laughing.
"Down the hatch," he said, finishing his drink. "Tomorrow morning I'll be lying on a curb in Minsk."
Instead, Costas is resting, hoping his pinkeye improves.
