Theo Walcott has received a set back in his recovery from injury and will miss at least another two weeks.

The Arsenal attacker has been suffering groin and stomach muscle injuries but broke down in training last Thursday despite being on the verge of a return to action.

The Gunners host Borussia Dortmund in the Champions league tomorrow, a game Walcott will defintely miss while he is also set to miss Premier League matches against Crystal Palace and Chelsea.

The Gunners' fantastic form this season continued on Saturday, with a 4 - 1 win over Norwich - a result that included a dazzling opening goal finished off by Jack Wilshere.
