William Levy, one of the front-runners this season on Dancing with the Stars, hurt his ankle in rehearsals Sunday and is questionable for Monday's performance show.
"Just Wanted to let u know that I injured my right ankle pretty bad during rehearsal.. MRI tomorrow. I'll let u all know .. Love u all," the Cuban heartthrob Tweeted.
The actor, 31, PEOPLE's cover boy this week, got high marks from Dancing's judges for the first three weeks, before earning less glowing reviews last week for the jive.
Nonetheless, he has taken the ballroom by storm, with partner Cheryl Burke telling PEOPLE: "I have never heard it that loud in there. He's like a rock star!"
