Sunderland have confirmed Fraizer Campbell is likely to miss most of next season after being booked in for a knee operation.
Campbell has endured a nightmare season on the injury front after damaging his cruciate ligaments against Manchester City back in August.
He was working towards a first-team comeback only to twist his knee during the build-up to the return fixture against City earlier this month.
Black Cats boss Steve Bruce revealed his fears last week that the former Manchester United striker's latest injury could lead to him missing much of the 2011/12 campaign.
The 23-year-old will now undergo surgery on Wednesday and it appears likely to be next year before Campbell will pull on a Sunderland shirt again.
The confirmation of the extent of Campbell's injury follows on from the news on Tuesday that goalkeeper Craig Gordon will be out for up to six months after having knee surgery.
Bruce said in The Journal: "Fraizer is going to be operated on in London. It's another one to add to the list.
"That is six operations we've had this season, with Craig. We're having a drastic time off the pitch."
He addded in the Sunderland Echo: "He will be out for 12 months.
"He was out on the training ground yesterday having a bit of banter with the players. He's taken it okay because he is strong mentally.
"Thankfully, with his strength of mind, we think he will be okay. I hope he will be. If there's anyone mentally tough enough, it's him."
Campbell's injury leaves Bruce desperately short of attacking options for Sunderland's game against fellow strugglers Wigan Athletic on Saturday.
Darren Bent's January sale had already reduced Bruce's strike-force, while an injury to Danny Welbeck means Asamoah Gyan is the only senior forward available for the visit of the Sunderland manager's former club.
Meanwhile, goalkeeper Trevor Carson has been recalled from his loan spell at Brentford to provide cover for Simon Mignolet as Gordon prepares to begin his rehabilitation.
