Injured five-time "Dancing With the Stars" champion Derek Hough will be unable to perform his role in Radio City Music Hall's "New York Spring Spectacular" for the foreseeable future, and it is uncertain if he can perform on Monday's edition of "DWTS."

"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," Hough spokeswoman Susan Madore told Newsday in a statement. "Derek will remain in Los Angeles this week to rehab his injuries and his understudy will be filling in for him for 'New York Spring Spectacular' at Radio City Music Hall in New York. 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."

Madore confirmed ABC's earlier statement that Hough, 29, was injured while rehearsing for the "Dancing With the Stars: 10th Anniversary Special" airing Tuesday.

Radio City had announced Wednesday that Hough's role as Jack, an angel out to save an old New York City tour guide's job, will continue to be played by Taylor Frey, who stepped into the role with Wednesday's 2 p.m. performance. The show, which also stars the Rockettes and Tony Award-winner Laura Benanti, is scheduled to run through May 7.

Hough, 29 -- who on Monday had posted and then deleted an Instagram image of himself in a wheelchair with most of his left foot wrapped and held by splints, and his right foot encased in a therapeutic boot -- recently posted a new image showing himself and Liukin from Monday's show, overlaid with the words "Your SETBACK is a platform for your COMEBACK."
