While riding a bicycle:

(March 23) – You can’t make this stuff up, folks. Matt Lauer was MIA on the ‘Today’ show Monday after running into a deer while riding his bike over the weekend, his co-host Meredith Vieira told viewers.
“Matt’s banged up with a displaced shoulder, it popped out,” she said. “So hopefully he’ll be on the mend soon.”Lauer, she told viewers, “thinks the deer was hired by the competition.” No dice, Vieira countered. “I hired the deer, but I said, ‘Just graze him.’”
