The Dancing Guy took a little spill during Monday's performance on "Dancing with the Stars," injuring his knee on the landing.
"I stepped on the cuff of these fancy slacks and I went down, I fell down," he explained. "And so, in professional sports, we say, 'He's day to day, day to day."
"We'll do R.I.C.E.-- we'll do rest, ice, compression, elevation -- and see where we get," he said, after the performance."
As it turned out, day two involved a visit to the hospital, where a doc delivered the bad news.
"Here is the scoop: partially torn ligament," Nye wrote on Instagram. "Awaiting the doc's orders with Tyne. We plan to dance! Stand by."
