The Irish’s corner had no choice but to pull him out of the bout, with Donaire becoming the WBA bantamweight champion.
After seeing his opponent leave the ring on a stretcher, Donaire was quick to send his best wishes.
He told reporters: “As a warrior, Burnett is an amazing fighter, early on he just kept coming at me. A win is a win and it wasn’t the way I would like to win but he’s an amazing fighter.
“Age is nothing but a number. He was fast, strong and caught me with some good punches. I came into this fight as the bigger guy and my coaches snapped me out of it and told me to box. “I then started to use my speed and fight the way I usually do, which is the Filipino Flash.”
