Sunderland manager Steve Bruce has revealed that strikers Asamoah Gyan and Danny Welbeck are likely to miss the rest of the season through injury.
The duo were both withdrawn with hamstring injuries during Saturday's 4-2 win against Wigan and leave the Black Cats short of striking cover.
"We're unlikely to have Gyan and Welbeck for the rest of the season," Bruce told BBC Newcastle.
"It was nice to win, but we're training with 13 fit players now."
Bruce's options have been severely affected by the loss of Gyan and Welbeck, with Fraizer Campbell already a long-term absentee after undergoing a knee operation earlier this month.
Those injuries, added to Darren Bent's departure to Aston Villa in January, mean that 18-year-old Ryan Noble is the club's only recognised striker.
However, the Wearsiders' manager could revert to the unorthodox partnership of Stephane Sessegnon and Steed Malbranque that ended Saturday's victory at the Stadium of Light.
"The problem with Ryan is that he hasn't played a lot of football, and he's got a youth team game tomorrow," Bruce added.
"I will look at it, because the one area we did do well and we played very well at the start of the season, was when we had Steed Malbranque off the front, and he gives us something different.
"In my mind, we scored three with Malbranque and Sessegnon up front, so maybe that's the way we'll go."
Gyan arrived at the Stadium of Light from French side Rennes for a fee in excess of £13m in August last year, while Welbeck is on a season-long loan from Manchester United.
