Host/TV personality Bob Costas attends the 2012 Golden Goggle awards at the Marriott Marquis Times Square on November 19, 2012 in New York City. Costas will be back Monday to host NBC's primetime coverage of the Sochi Games.
NBC's Bob Costas plans to make his return to NBC on Monday after being off the air for a week with an eye infection.
NBC said Sunday that "Today" host Matt Lauer will sub for Costas one last time on NBC's Sunday night telecast, and that Costas is preparing for his return in prime-time Monday.
The long-time Olympics host started duty in Sochi with one eye reddened from an infection that he hoped would clear up quickly. Instead, it spread to his other eye. It made his vision sight blurry and it was difficult for him to work, and his red eyes were a popular topic on social media.
Lauer and Meredith Vieira have filled in for him.
