Lauer was riding his bicycle this weekend when a deer jumped into his path. He flipped over the bike's handlebars and was slightly hurt, NBC said.
His broadcast partner, Meredith Vieira, joked on the air that Lauer thinks the deer was hired by the competition.
"Matt's banged up with a displaced shoulder, it popped out," she said. "So hopefully he'll be on the mend soon."
Lester Holt filled in as Vieira's co-host Monday.
