Arsenal will be without Nicklas Bendtner for tomorrow's Champions League game against Olympiakos after the striker was involved in a minor car accident.
Manager Arsene Wenger said: "Nicklas did not practice because he had a car accident yesterday.
"Fortunately there was no real long-term damage, but he was bruised and we thought it better he did not train.
"He should be back for Sunday's game [against Blackburn]."
England forward Theo Walcott is expected to return from a back problem in time for the weekend, but Denilson is set for up to two months on the sidelines with a fracture to his back.
Goalkeeper Manuel Almunia is still troubled by the chest infection, so Vito Mannone will continue in his place following man-of-the-match display against Fulham.
Bendtner, 21, was driving along the A1 yesterday morning towards South Mimms when his car left the road.
It is understood no other vehicle was involved in the incident and a Hertfordshire police spokesman said: "We were called at 10.15am to a report of a single vehicle road traffic collision.
"A black Aston Martin vehicle had left the road. The driver was not seriously injured."Reuse content
