The Chilean actor suffered a severe pain in his left arm while performing the samba live on ABC's "Dancing With The Stars." It was his second dance of the evening.
An announcement about his condition will be made on Tuesday night's results show, the spokeswoman said.
De La Fuente did his best to complete the dance, but was unable to hold on to his partner, Cheryl Burke, as she crumpled to the floor in the routine's final move.
Broadway star Marissa Jaret Winokur continues to improve, winning praise for her tango and rumba. She earned her highest score yet, a 27, for the tango.
Judge Carrie Ann Inaba thought her rumba was beautiful and gave her a 9. Judges Len Berman and Bruno Tonioli said the routine wasn't sexy enough and each gave her an 8.
The season's front-runner, Kristi Yamaguchi, showed she isn't bulletproof, earning her lowest score so far. The judges gave her a 26 for her Viennese waltz, which opened with Yamaguchi holding an umbrella as she danced. Goodman said the routine was too long and that he didn't like "all that mincing about with the umbrella."
The traditionalist judge didn't like her mambo any better, especially because there were a few hip-hop moves in the routine. Tonioli and Inaba each gave it a 10, but Goodman gave it an 8.
After being told she had no hip action in last week's rumba, Shannon Elizabeth made a comeback with this week's tango. Goodman said it was terrific, and Inaba said it was her best routine yet. She earned a 27 from the judges.
The judges said the long-limbed actress looked gangly at times during her mambo. They told her to work on her lines. That means, for example, fully straightening her knee and pointing her foot so her leg makes one straight line. She scored a 24 for her mambo.
The judges said Mario may not have the elegance required for a professional-level fox trot, but they just love to watch him dance. He earned a 24. He came alive in a traditional mambo that the judges rated a 27.
The dancers return Tuesday night to find out who will be sent home after the viewer votes are combined with the judges' scores. The rather un-ballroom like Def Leppard is the scheduled musical guest.
