Costas phoned Matt Lauer Tuesday on "Today" to ask him to cover the network's Olympics coverage at night.
"Reluctantly, I was trying to throw a complete game here, but I think we're going to have to go to the bullpen, and I don't know if you're aware of this or not, but you're Mariano Rivera, at least tonight,'' Costas told Lauer. "Let's hope it's only tonight. I'm walking around, I might as well be playing 'Marco Polo.' I have no idea where I am.''
Costas's infection seemed to be getting to him Monday evening, when he downed a glass of vodka on air with fellow NBC host Mary Carillo.
"I'm looking at it this way though, my eyes can't get any redder," he said. "No matter what I do."
"By the way, I will be doing the shots of vodka starting in about 15 minutes,'' Lauer joked after accepting the challenge.
