Say it ain't so! Dancing with the Stars' Derek Hough has suffered foot and ankle injuries that could have him sitting out the rest of the season.

"While rehearsing for the 10th Anniversary Dancing with the Stars television special Monday night in Los Angeles, Derek Hough suffered injuries to his right foot and left ankle," Hough's rep said in a statement released to TVGuide.com. "He has been diagnosed with a broken toe on his right foot and sprains to his left ankle on both the inside and outside aspects and a bone bruise on the same ankle."

The statement continues, "While it remains unclear at this time if Derek will be able to perform on the Monday, April 27 episode of Dancing with the Stars, his partner Nastia Liukin will train in Los Angeles this week with pro-dancer Sasha Farber to prepare for the Live show."

Meanwhile, Hough's understudy will take his place in the New York Spring Spectacular at Radio City Music Hall in New York.

Hough weighed in on the situation via Instagram, explaining that he was not taken down by dancing or flipping, but by "a light and some stairs." He also noted the rough rehearsal schedule that and Liukin have had to contend with all season, due to his role in the Radio City show.

"This is new territory for me," he wrote, "I'm usually able to work through injury but this one has literally floored me. But like I said before, I'm determined to come back all guns blazing...soon!!!"
