Manchester United striker Ole Gunnar Solskjaer has suffered a new setback in his bid to recover from a knee injury.
The 32-year-old Norwegian last played for United in the FA Cup Final win against Millwall in May 2004.
Swedish knee specialist Lars Petersson said: "He has picked up a tear inside his knee. It is a very recent injury."
Petersson operated on Solskjaer last year, and added: "I thought he might be back in October but it is impossible to set a date now."
And asked whether he was totally confident Solskjaer will come back at all at the top-level, Petersson added: "No. I am never 100% sure in these cases."
A spokesperson for Manchester United said the club would not comment on the report.
