Bill Nye is reportedly in "good spirits" after suffering a partial ligament tear in his left knee in a fall during his dance routine Monday on ABC’s "Dancing with the Stars," reports People magazine.

Nye, known as TV’s "Science Guy," fell after he "stepped on the cuff of these fancy slacks and I went down," he told the publication.

"We’ll do R.I.C.E. — we’ll do rest, ice, compression, elevation [and] see where we get," he said of his injured knee.

As previously reported, Nye was injured while dancing with partner Tyne Stecklein. He has become a fan favorite with his goofy performances, including Monday night’s segment, when he dressed as Ludwig van Beethoven and danced to the composer’s Fifth Symphony.

Nye sent out a tweet Tuesday saying: "Here is the scoop: partially torn ligament. Awaiting the doc’s orders with Tyne. We plan to dance! Stand by…" He also sent around an Instagram photo (shown below).

The New York Daily News reports: "The 57-year-old TV geek partially tore a ligament in his knee, apparently sustained during a trip at the end of his routine [Monday]." He was reportedly rushed to the hospital after the performance.

Nye has received low scores on the show for his dancing, but has ranked high in popularity, the Daily News notes.

"Nye and partner Tyne Stecklein have leaned heavily on the Science Guy’s comedic timing and TV persona in their routines so far on ‘DWTS.’" the piece reports. "A gimpy knee plus a spot at the bottom of the leaderboard is not a potential winning formula for the Science Guy. Nye, however, avoided elimination on ‘DWTS’ Monday night, despite fielding the worst scores this season."

Nye was not optimistic — at least about his dancing — in the runup to his "Dancing with the Stars" stint, telling Entertainment Weekly just before the season premiere: “I’m pigeon-toed, I’m on the wrong foot, and I’m slouched — I mean when you look in the mirror, I suck. I suck. But with that said, at least I’m aware of it.”

The Daily News adds: "His best moves have been off the dance floor: galvanizing the popular vote and dominating the rest of the field in social media mentions to keep himself in the game. If Nye needs surgery, he’ll likely have to step down from the dance competition — following the footsteps of past season casualties Dorothy Hamill (spine) and Misty May-Treanor (torn Achilles’ tendon)."
