Kell Brook's trainer has revealed that the boxer is "stable and on the mend" after being stabbed while on holiday in Tenerife.
The IBF welterweight champion was taken to hospital on Thursday after he was stabbed in the left leg.
Brook's trainer, Dominic Ingle, revealed that the 28-year-old has undergone surgery and is on the road to recovery, but stated that it is too early to tell if and when he will be able to return to the ring.
Ingle told BBC Radio Sheffield: "He had an operation after the stabbing and he's now stable and on the mend. Hopefully today when the dust settles we will know a bit more.
"They've done a good job repairing him and they've stitched him up, but we'll just have to assess the damage when he comes back."
Ingle is in the dark as to why Brook may have been targeted as he took time out following his victory against Shawn Porter in California last month.
"After a fight you want to relax, switch off - you let your guard down and innocent situations can turn rapidly into something else if you're not careful." Ingle said.
"It seems somewhere along the line Kell Brook's let his guard down and this has happened,"
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.
Brook was previously the victim of a stabbing while on a night out in Sheffield in 2007.
