Fans who had tuned into NBC Sports’ coverage of the Kentucky Derby on Saturday, May 3, grew concerned for host Mike Tirico when he suddenly left the broadcast. NBC Sports correspondent Ahmed Fareed took over for Tirico, alongside Carmelo Anthony, sharing only that Tirico started to feel under the weather.

Tirico said his nose and throat "clogged up" and swelled. He added that the allergy can affect your breathing as well. Tirico decided he could not perform his duties as a broadcaster due to the reaction. He took an EpiPen shot — a common treatment for people experiencing an allergic reaction — and was seen by EMTs.
