Updates from Thursday, March 13
Kim Kallstrom is expected to hand Arsenal a boost by declaring himself fit for the weekend trip to Tottenham.
The Telegraph's Jeremy Wilson reports:
(Aaron) Ramsey, Theo Walcott and Jack Wilshere are also sidelined while Kieran Gibbs’s injured ankle must still be assessed before his availability on Sunday is decided.
The brighter injury news is that midfield loan signing Kim Kallstrom should be available to make his debut following a back fracture while Yaya Sanogo, Nicklas Bendtner and Nacho Monreal are also all expected to return.
Arsene Wenger refused to rule out the Swede's debut on Thursday, telling the club's official website:
Kallstrom joins the normal training group today and Sanogo too. I will have to decide if Kallstrom is OK to be in the squad on Sunday. I will see how he looks, it is not impossible.
Updates from Friday, March 7
Kim Kallstrom will not feature in Arsenal's FA Cup quarterfinal with Everton.

Kim Kallstrom might be ready to make his Arsenal debut in their weekend FA Cup quarterfinal against Everton, reports the Mirror's John Cross:
Swedish midfielder Kallstrom, 31, who joined Arsenal in January despite having a back injury, is nearing match fitness.
Kallstrom even has an outside chance of making the squad to face Everton in Saturday's FA Cup tie after telling the Swedish FA's medical staff he is "close to being fit."

One day after Arsenal added Kim Kallstrom on loan from Spartak Moscow at the transfer deadline, the 31-year-old midfielder was injured in training.
The Daily Mail passed along word of the frustrating turn of events for the Gunners and report he could miss up to three months:
BREAKING: Arsenal's new signing Kim Kallstrom is out for two-three months after picking up an injury in his first training session. WOW.— MailOnline Sport (@MailSport) February 1, 2014
Arsenal are saying the initial timetables being reported are off-base, however, with the only confirmation being he won't play against Crystal Palace, according to the Telegraph:
Arsenal deny Kim Kallstrom injury is serious, saying he has a slight back problem and will not be in the squad against Palace tomorrow— Telegraph Football (@TeleFootball) February 1, 2014
The Daily Mirror confirmed the report and added more details on the injury:
Latest: Kim Kallstrom arrived at Arsenal with minor back injury. He did NOT pick up a problem in Gunners training http://t.co/9mTLcYg8p1— Mirror Football (@MirrorFootball) February 1, 2014
David Ornstein of BBC Sport provided more details on what exactly happened to the veteran midfielder:
Midfielder Kallstrom, 31, is set to miss at least six games.
The Swede was hurt on Tuesday while playing football on a beach during Spartak's pre-season tour in Abu Dhabi.
He told Arsenal of his discomfort on arrival at the club on Friday but despite an MRI scan showing no damage, a CT scan found an issue with his back.
The Arsenal medical team provided manager Arsene Wenger with the prognosis, but it was decided Kallstrom would still join and undergo his rehabilitation with the Gunners.
The Gunners spent a vast majority of the transfer window seeking ways to upgrade their depth in the midfield. When the dust settled after deadline day, Kallstrom was the player Arsene Wenger believed was the best fit considering price, availability and experience.
Ornstein noted that Kallstrom was looking to make an impact:
Arsenal is an amazing club with a lot of great players and a coach who has done really well here for a long time.
I am so pleased to come here to learn as much as possible. I'm here to do my best for Arsenal and to help out the team, so we can achieve good results for the last part of the season.
Now it's unclear when he'll be able to help Arsenal. More information on his status will be provided when it's made available by the club.
