SOCHI, RUSSIA -- NBC News and TODAY correspondent Meredith Vieira will fill in for Bob Costas as host of the NBC Olympics primetime show on Friday night, making history as the first time a woman has ever solo hosted Olympics primetime coverage.
Costas, who until Tuesday night had hosted every NBC-aired Olympic primetime show since 1988, has been battling an eye infection since arriving in Sochi and has not hosted the show since Monday night. TODAY host Matt Lauer filled in for Costas from Tuesday through Thursday night.
