Sunderland have been handed a major boost with the news that injured striker Kenwyne Jones could be back in action within the next two months.
The 23-year-old was injured during Trinidad & Tobago's friendly against England in June, with the Black Cats having to wait until now to learn the full extent of the problem.
Manager Roy Keane told the club's official website: "Kenwyne had his operation yesterday.
"Fortunately, we've avoided major surgery and expect him back in training in the next six to eight weeks.
"You never know the full story until you go into the knee, that's why we've been open in terms of the prognosis.
"But it's great news for everyone at the club, Kenwyne is a big player for us."
Sunderland had initially feared that Jones could miss most of the season, with the giant frontman having scored seven goals in 33 appearances in his first season at the Stadium of Light.
Jones joined the Black Cats for £6million from Southampton last summer, while he has also enjoyed loan spells with Sheffield Wednesday and Stoke City.
