The Voice UK favourite Jaz Ellington could be a shock exit tonight, as he suffers from a chest infection.
The singer will be performing in the battle rounds against Jay Norton for a spot in next weekend's first live show.
But Jaz, who last Saturday reduced Will to tears, shocks the Black Eyed Peas star by revealing he is struggling with his health.
Will's mentor Dante Santiago steps up to give him some advice, telling Jaz: "You've got to carry. I remember once, I was sick, I had a fever running 102 degrees, but I went out, Prince was in the audience, and it was one of the best gigs I've ever done."
Before going on stage, Jaz confides to the camera: "I don't know how my voice will cope with this.
"I'm nervous, I'm going to go out there but I'm not sure what's going to come out."
Will Jaz's voice survive the battle? Tune into the show at 7PM tonight on BBC One.
