Arsenal manager Arsene Wenger welcomes back Theo Walcott and Denilson for Wednesday's Barclays Premier League visit of Bolton but looks set to be without Samir Nasri and Aaron Ramsey for three weeks.
England star Walcott has been struggling with a rib injury while Brazilian Denilson has been hindered by an abdominal problem but both will be in contention to face Owen Coyle's Trotters in the rearranged match at the Emirates Stadium.
"They are available for Wednesday night. It is a big boost to have them back of course because they were out for a while and it gives us some fresh players as well and it's very good," Wenger told Arsenal TV Online.
"He (Walcott) was unlucky with some small niggling injuries and now it is good to have him back."
Nasri and Ramsey picked up knocks before Sunday's 2-0 league win at Bolton and are likely to need three weeks to recover, although Wenger is optimistic they could be back earlier than that.
"Samir Nasri and Ramsey are both out for 21 days," the Frenchman continued. "Let's say we can have a good surprise with both because they are usually quick recovering players but our common sense tells us 21 days."
Wenger is also hopeful Nicklas Bendtner will be back in action soon.
The Danish striker has not played since the end of October due to a groin injury but the Gunners boss thinks he will be available for the Premier League trip to Villa Park on Wednesday week.
"Nicklas Bendtner should be back for the Villa game," said Wenger. "He should be available from next week onwards. Maybe not completely ready for Stoke (in FA Cup fourth round on Sunday) but after that he should be able to be in the squad."
