"DWTS" contestant and "Extra" host Maria Menounos told Mario Lopez Monday that she's worried about dance partner Derek Hough's ability to perform in tonight's semi-finals.
When Mario asked if Derek would be able to perform on Monday night, Maria said, "I don't know. I'm getting updates as of now that he's in a lot of pain and is going to wear a back brace. He couldn't shift it at all… I'm going to pray for the best."
Maria tweeted a picture Monday of a bandaged Derek with the caption, "So nervous about tonight. Derek is in rough shape...getting him fixed up as I tweet."
Derek is no stranger to injuries during crunch time. In 2010 he suffered a neck injury before performing in the finale with partner Nicole Scherzinger.
