IBF world welterweight champion Kell Brook has "lost a lot of blood" but is in a stable condition in hospital after being stabbed during an attack at an Tenerife apartment complex while on holiday with his pregnant wife.
The 28 year old's injuries are not thought to be life-threatening though Brook is understood to have suffered a stab to the leg and a cut to the arm at around 6am on Thursday morning while staying on the Spanish island.
Police were called to the accommodation at 8am and Brook was subsequently taken to hospital in the island's capital Santa Cruz where he is currently recovering.
A spokeswoman for Spain's Guardia Civil said: "This morning a 28-year-old British man was stabbed at Golf del Sur in San Miguel de Abona. He was stabbed in the left leg and is hospitalized. He lost a lot of blood. There are no arrests at this time and the Guardia Civil are investigating."
Matchroom Boxing, the Briton's stable, are still to officially comment on the incident but chief Eddie Hearn told The Daily Mail: "I will flying out tonight to see what is going on. We are all worried about what has happened. 'There are a lot of stories out there so let's just wait and see. I am told he is stable."
The British Boxing Board of Control are also still to comment as they gather the full details of the episode. Brook had been relaxing on holiday with his pregnant partner Lindsey Myers, who is expecting their second child.
The news comes less than 24 hours after Matchroom promoter Eddie Hearn confirmed that Brook and fellow-Briton Amir Khan were close to agreeing to a fight at Wembley Stadium in 2015. An imminent fight between the pair has now been thrown into doubt.
Brook became the first British fighter in 28 years to win a world title in the United States in August after a majority points victory over Shawn Porter in California.
Unbeaten during his professional career with a 33-0 record, Brook had targeted future bouts with Khan and American Floyd Mayweather after winning his maiden world title last month.
The Sheffield-born fighter suffered side and buttock injuries after being stabbed in his home-town in 2007 but was side-lined from boxing for just six months.
The incident follows former European champion Jamie Moore being shot five times while on holiday in Marbella in August.
Speaking to Sky Sports, Moore said of Brook: "It's shocking to be honest. Obviously there is no real information over what has happened and why. All I can say is I hope it's not too serious and hope for a safe recovery. It's a bit scary to be honest, I just hope he is ok."
Brook is set to return to the ring for a homecoming fight as the newly crowned world champion on 6 December.
