Bill Nye The Science Guy may need science to continue dancing.
Nye -- who's appearing on this season's 'Dancing With The Stars' -- tripped at the end of his paso doble Monday.
He appeared to be fine and walked over to the judges' table for his score.
But according to the Associated Press, he may have seriously injured himself.
Nye posted an Instagram photo of 'Dancing' partner Tyne Stecklein and himself -- sporting a heavily bandaged leg.
"Here is the scoop: partially torn ligament. Awaiting the doc's orders with Tyne. We plan to dance! Stand by..." Nye posted.
Nye, who is considered to be a fan favorite, is at the bottom of the leader board.
