Arsenal have been stunned by news of Theo Walcott suffering an ankle injury in England training.
Walcott hurt an ankle during training with England on Monday, needed to be helped from the pitch and could not complete the session.
Arsenal winger Walcott is now a doubt for Wednesday's international friendly against Scotland - and his club boss Arsene Wenger will be anxious no risks are taken ahead of the Gunners' season-opener against Aston Villa.
England coach Roy Hodgson said: "Theo took a slight knock at the end of training, but we believe he'll be okay. He's very much still in contention."
