Kell Brook has vowed to make a full recovery after undergoing surgery following an "unprovoked attack" in which he was stabbed in the leg.
The IBF welterweight champion was taken to hospital on Thursday after he was wounded in his left leg while on holiday in Tenerife.
It was revealed by Brook's trainer, Dominic Ingle, that the 28-year-old had required a "life-saving operation", but Brook was defiant when he spoke from his hospital bed in Spain on Friday.
"I was out enjoying a night out before returning home to the UK when I was the victim of an unprovoked attack," he said.
"I'm devastated right now after being on such a high having achieved my dream of becoming World Champion in Los Angeles last month.
"This is obviously a major setback but the thought of defending my title is what's keeping me positive right now. I want to thank everyone for their support and ask for privacy for myself and my family at this time.
"Make no mistake " I will be back."
The incident will raise doubts over plans for a fight between Brook and fellow British fighter Amir Khan in the near future.
Promoter Eddie Hearn had confirmed on Wednesday that discussions over the pair going toe-to-toe at Wembley in May were under way.
Hearn added: "We were all glad to get out here and see Kell for ourselves. The important thing now is to get him home and after some rest begin physiotherapy on his injuries.
"His first defence was planned on December 6 which is now unrealistic but we fully expect Kell to be back in the ring early next year."
Brook, who is set to return home to Sheffield on Monday, was previously the victim of a stabbing while on a night out in his hometown in 2007.
