Jason Derulo fractured his neck during rehearsal and cancelled the world tour

R&B star Jason Derulo has narrowly avoided paralysis after falling directly on his head during a rehearsal for his world tour.

Jason Derulo, 22, was practicing a dance routine for his concert when the accident happened.

The singer landed badly and suffered an acute fracture to his vertebrae, miraculously avoiding paralysis.

Jason Derulo was rushed to a hospital in Pembroke Pines, Florida where he posted a photo of himself onto his Twitter page.

Doctors have ordered Jason Derulo to wear a neck brace for the next few months, meaning that he has had to cancel his world tour.

Jason Derulo told his Twitter followers: “I fractured my neck doing tumbling & acrobatics 4 tour!

“Always tryin 2 push boundaries 4 YOU!”

Perhaps in reference to his neck brace Jason Derulo then tweeted: “Like my new chain? ;)”

The singer later explained the injury to his fans on his Facebook page, saying: “My injury is called a <<Hang Man’s Break>> because it is the same bone that is broken when someone is hung!

“I am so blessed to still be here.

“95% of ppl [sic] with the same injury end up paralyzed or gone. Everything happens for a reason.

“Traumatic experiences can change you for the better.

“My outlook on life is so much clearer! Don’t forget what’s important.

“Life is short so do it today, tomorrow could be a day too late!”

Jason Derulo was preparing to kick off his Future History world tour, which was named after his album.

His world tour was supposed to begin in Glasgow on February 23.

Jason Derulo’s record label has issued a statement from him in the wake of the accident.

In the statement he says: “To all my fans who planned to come to the Future History world tour, the pain of letting you down cuts me way deeper than this injury I’ve sustained.

“My fans mean everything to me so I’m praying for a speedy recovery in order to perform for you in the near future.”

Jason Derulo has since been released from hospital.
