Midfielder Frank Lampard will miss Chelsea's Barclays Premier League clash with Arsenal at Stamford Bridge on Sunday with a groin problem.
Lampard has recovered from hernia surgery but has since sustained a slight groin problem.
Ivory Coast striker Didier Drogba is back after being suspended for the midweek Champions League game against Marseille. Chelsea are also without injured striker Salomon Kalou (thigh) and midfielder Yossi Benayoun (calf).
Chelsea's assistant boss Ray Wilkins insists the Blues must combine strength with skill if they are to avoid a second successive Barclays Premier League defeat.
Wilkins admitted his side were out-muscled by Manchester City at Eastlands last weekend when Carlos Tevez's goal handed them their first defeat of the season.
Arsenal boss Arsene Wenger says his side must resist being "dominated" by the defending champions, but Wilkins has already vowed his team will use power as well as talent to prevent another setback.
"The Manchester City game was exactly the same as last year in that we didn't compete as well as we should have done," said Wilkins.
"We did not compete in a physical sense, that is why we lost the game last year and for me that is why we lost the game this year, and that is not like us.
"I thought City's Nigel De Jong was the best player on the pitch and they took us by surprise and should not have done.
"But that will not happen again. We have to find the happy medium between, strength, power, the physical side of stuff as well as playing football. That is what the Premier League requires. We must make sure we are up there in every aspect throughout the season.
"You have to be ready for the physical side and combat it. We didn't combat that against Manchester City and we lost. Some you days you play poorly. It is just human nature."
Arsenal will be without captain Cesc Fabregas (hamstring) while England Under-21 full-back Kieran Gibbs (calf) is also sidelined.
Goalkeeper Manuel Almunia (elbow) remains out, meaning Lukasz Fabianski is again set to deputise after impressing in the midweek Champions League victory at Partizan Belgrade, while midfielder Abou Diaby returns to the squad after an ankle problem.
Thomas Vermaelen (Achilles), Nicklas Bendtner (groin), Aaron Ramsey (leg), Theo Walcott and Robin van Persie (both ankle) are still absent.
Arsene Wenger maintains it is vital Arsenal win the head-to-head battles against their Barclays Premier League title rivals this season.
The Gunners suffered a shock home defeat to West Brom last weekend, although quickly got that out of their system with a hard-fought 3-1 victory away to Partizan Belgrade in the Champions League on Tuesday night.
Another loss at Chelsea - themselves beaten at Manchester City - would leave Arsenal seven points adrift of the leaders, and potentially out of the top four should other results go against them.
Last season, Arsenal were beaten home and away by both Chelsea and Manchester United, with a double over fading Liverpool little consolation.
Their next away match is Manchester City after the international break on October 24.
While Wenger knows nothing will be decided tomorrow, the Arsenal manager concedes the clashes between the leading contenders have taken on extra significance.
"The only team I have seen win the Premier League without winning the big games is Manchester United," he said.
"It is vitally important to win the big games."
Wenger added: "It is easier to play Chelsea on Sunday when they have lost two games than two weeks ago, that is for sure.
"Every defeat makes you just a fraction smaller."
