James Vaughan has finally undergone surgery to his right knee, four weeks after twisting the joint in training.
Vaughan had travelled to Colorado earlier this month to again visit American specialist Richard Steadman. It was the renowned surgeon who operated on Vaughan after the 20-year-old had endured serious problems with his left knee, but Steadman was forced to cancel the latest surgery after breaking his arm in a skiing accident.
That forced Everton and Vaughan into seeking help in England, and Everton assistant manager Steve Round said: "James had his operation on Wednesday and everything went very well. We now wish him a speedy recovery, and hopefully he should be fit before the end of the season."
He added: "But we will have to keep a tab on that and see how it goes over the next few weeks."
Vaughan is one of four Everton strikers currently out of action, although Victor Anichebe and Louis Saha are both closing in on a return.
Anichebe missed the 1-0 win at Manchester City with a back injury last weekend, whilst Saha has sat out the last three weeks with hamstring trouble.
Both players are due to undergo fitness tests over the weekend with regard to the possibility of figuring in Monday's game with Chelsea at Goodison Park.
Everton assistant manager Steve Round, meanwhile, is delighted to see Allardyce back in the big time after he was appointed Blackburn manager on Wednesday.
Round, who worked with Allardyce at Newcastle for six months prior to the latter's dismissal, said: "I'm really pleased for him.
"He is a good friend of mine, was once a colleague, but most of all he is an exceptional manager. He is also a good guy, and the Premier League is a better place for him being back."
