ABC has confirmed that Bill is currently seeking medical attention for his injury.
In a statement, the network said, "We can confirm Bill Nye was injured during his performance last night and is currently seeking medical attention. We will continue to keep you posted on his progress."
RumorFix has reported that the injury involves his knee and he is having an MRI done. Depending on the severity of the injury, surgery is possible.
If he does drop out of the competition, there will most likely be no elimination next week. Due to his popularity, Bill most likely would have stuck around a few more weeks in the competition.
See his Paso Doble from last night. He falls just after the 3:06 mark. Bill does a great job of covering the fall though, he's a true performer.
