The 22-year-old award-winning singer and songwriter - who is best known for hit singles such as 'Fight for You' and 'Breathing' - told his fans that he felt terrible to let them down, but had no option but to axe his performances.
Warner Bros Records issued a press release from Derulo which read: "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."
The musician sustained the neck injury on Tuesday, January 3 when he landed directly on his head after an acrobatic move during rehearsals for the tour.
He was rushed to hospital and told by doctors that he had an acute fracture to his vertebra and could have been left paralysed.
Although Derulo has since been released from Memorial Hospital West in Miami's Pembroke Pines, he has been advised to wear a neck brace for the next few months.
Warner Bros Records said that any ticket holders will receive full refunds at point of purchase.
