NBC’s Mike Tirico opened up after he was forced to cut his coverage of the Kentucky Derby short over the weekend due to his sever nut allergy being activated.

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.
