Chelsea's reserve goalkeeper Ross Turnbull will make his Premier League debut for the club against West Ham United tomorrow after injury ruled out their first and second-choice keepers.

Carlo Ancelotti's side will be without Petr Cech and Hilario as they try to reclaim top spot in the Premier League from Manchester United. Hilario was ruled out with a groin injury, having been deputising for Petr Cech who is sidelined with a calf injury.

Chelsea, who are two points behind United with a game in hand, will also be without their Portuguese central defender Ricardo Carvalho.

"Hilario is not able to play tomorrow, so in goal will play Turnbull," the Chelsea manager, Carlo Ancelotti, told the club's website. "We don't know if Hilario or Petr will be able to play [in the Champions League against Internazionale] Tuesday, but Carvalho I think will have no problem for Tuesday."

Turnbull will be making his first league appearance for Chelsea since signing from Middlesbrough.
