Manchester United captain Gary Neville will be out of action for another two weeks because of a calf strain.
Defender Neville has been out of action since 17 March
The 32-year-old England right-back missed the final two months of last season after undergoing ankle surgery.
But United boss Sir Alex Ferguson said Neville faces another fortnight on the sidelines with his new injury problem.
Ferguson also hopes striker Wayne Rooney, 21, will return within "eight or nine weeks" after fracturing his left foot against Reading on 12 August.
Rooney is currently in plaster but Ferguson confirmed the injury does not appear to be as serious as the England star's previous two broken metatarsals and is optimistic about the player's recovery time.
Ferguson added: "It is only a hairline but, with any kind of fracture, you have to make sure it is dealt with properly.
"It is always difficult to be accurate because everyone is different. I think Wayne should be back playing in eight or nine weeks."
Neville's new injury setback is expected to rule him out of the Premier League fixtures against Tottenham on 26 August and Sunderland on 1 September.
He could also miss England's Euro 2008 qualifiers against Israel and Russia in September.
Ferguson confirmed: "It will be another couple of weeks. We are frustrated with the situation because his operation was fine.
"The surgeons did find a few little bits in there, which they had to repair as well, and which meant a longer recovery period but then Gary suffered a calf injury.
"That sometimes happens when you are trying to compensate after an operation."
