Arsenal manager Arsene Wenger has confirmed that both Theo Walcott and Nacho Monreal will definitely miss tomorrow afternoon's trip to Stoke City, but Wojciech Szczesny could travel to the Britannia Stadium after being cleared to resume full training.
Walcott has been forced to spent further time on the sidelines over the last three weeks after picking up a groin problem training with England last month, a concern that has forced the Gunners to take fresh action.
Wenger has confirmed that in a bid to clear up the nagging injury Walcott will have an injection later today, and it that wasn't bad enough Kieran Gibbs and Laurent Koscielny are also struggling for full fitness.
Defensive concerns mounting once again
After confirming that Walcott is no closer to a first-team return Wenger moved on to more pressing concerns regarding a lack of options in defence, which threatens to ruin some new-found solidity at Arsenal on the back of three successive clean sheets in all competitions.
Wenger told the Daily Mail: "We have to assess a few players today because we had some bad surprises with Nacho Monreal being out for tomorrow’s game.

Should Wenger risk Koscielny?
"Hopefully Kieran Gibbs will be available and back in the team and we have to assess some other players like Laurent Koscielny and a few bumps and bruises that we got after the game on Wednesday. I’ll make that decision after training today."
Should Wenger decide Koscielny isn't up to a third full game in seven days and Gibbs shouldn't be risked the lack of quality alternatives will be a big worry for Arsenal, particularly given their struggles at the Britannia in recent times.
Mathieu Flamini or even Hector Bellerin could be forced to fill in at left-back, while Calum Chambers could be asked to fill in for Koscielny in arguably his more natural position at centre-back.
Mathieu Debuchy is back in full training but not ready to feature this weekend, with Tuesday's Champions League clash with Galatasaray offering a more realistic chance to see the French international.
With Alexis Sanchez on form and attacking options aplenty Wenger will still be confident of getting a result against a Stoke side who have struggled at home this season, but Arsenal's injury nightmare is far from over on the evidence of Wenger's latest press conference.
