Arsenal hit by Kallstrom injury blow

Kim Kallstrom is set to miss Arsenal's crucial upcoming fixtures with a back injury after signing for the club on transfer deadline day. 

The 31-year-old Swede, who has joined the Gunners on loan from Spartak Moscow, sustained the injury before arriving in north London and the club were aware of it before they completed the move.

Kallstrom, who was Arsenal's only January arrival, will miss the club's immediate upcoming matches but is not set to be sidelined for two to three months as has been reported in his native Sweden. 

Scans during the former Lyon star's medical on Friday confirmed an injury to the midfielder's back, which will likely see him miss crucial fixtures against Liverpool, Manchester United and Bayern Munich. 

The issue has kept Kallstrom out of training since his arrival at the club, with Arsene Wenger's men set to face Crystal Palace on Sunday. 

Aaron Ramsey and Jack Wilshere will both miss the visit of Tony Pulis' side to the Emirates, with Mathieu Flamini also out due to suspension.

Meanwhile,Manchester United defender Phil Jones suffered a concussion during the first half of the 2-1 defeat against Stoke City at the Britannia Stadium.

The centre-back clashed heads with Jonathan Walters and appeared to be knocked out before hitting the ground.

He was surrounded by medical staff and loaded onto a stretcher after around five minutes of treatment, before having a scan at a local hospital.

Danny Welbeck replaced his fellow England international, with Michael Carrick dropping into the defence alongside Chris Smalling.
Moyes also confirmed that Jonny Evans picked up a calf injury in the first 10 minutes.
