Austin Mahone's "MTV Artist to Watch Tour" has been cancelled after the singer was hospitalized on Thursday.

The 17-year-old singer is being treated for a blood clot in his throat. 

A rep for the singer said in a statement Friday that Mahone was admitted to the hospital Thursday with a 104 temperature. The rep adds that he's dealing with "extreme inflammation in his throat as well as severe dehydration." 

The tour is being pushed to next year. 

We wish Austin the best of luck and a speedy recovery!
