Chelsea have been boosted by the news that striker Didier Drogba's calf injury is not as serious as was first feared.
The 31-year-old Ivory Coast international limped off after scoring in last weekend's 3-0 win over Tottenham Hotspur and there had been fears that Drogba was facing a spell on the sidelines.
However, assistant manager Ray Wilkins told reporters: "Didier had a scan and there's no problem with his calf. It was just the most horrendous bout of cramp.
"We thought he couldn't release the muscle and it might be something more nasty, but he'll be able to take part on Saturday. It is very good news for us."
Meanwhile, Wilkins also confirmed that both Joe Cole and Zhirkov will feature in the Carling Cup third round clash with Queens Park Rangers this midweek.
He added: "We haven't finalised the side yet, but Joe Cole and Yuri Zhirkov will both start, which is good news.
"They'll be very important players for us as the season progresses. It's nice to see them come back in.
"When you can't use someone of Joe's ability, any side would miss him. He has that bit of fantasy that can open up defences, so we have missed him.
"But we've coped without him and now we'll have something different now he's come back.
"Zhirkov is a very fluid footballer. He's been out for quite a period but, if he demonstrates half of what he's shown in training, then we've got a very pleasant player on our books."
