Dennis Bergkamp will miss Saturday's game with Aston Villa because of a groin injury.
However there is better news about Sol Campbell (toe) and Freddie Ljungberg (calf). Both are likely to travel to Turin for the Champions League Quarter-Final second leg on Wednesday.
"Dennis is out with a tight groin," confirmed Arsène Wenger at Friday's pre-match press conference. "We also have out Ashley Cole, Gael Clichy, Pascal Cygan, Lauren, Sol Campbell and Freddie Ljungberg."
However, the latter pair will be back very soon.
"Yes, Sol will be back on Wednesday," said Wenger. "It is a boost to have him available again. He bruised his toe in training on Sunday after a challenge with Kolo.
"Freddie will be there [at Juventus] as well. Away from home we need fighters and experience. First we need to focus on Saturday's game, then we'll look at the next one to see if he will be on the substitutes' bench."
