Arsenal manager Arsenal Wenger has revealed Theo Walcott will not play again this season and will have shoulder surgery later this week. Surgery on the long-standing problem had been delayed because of other injury and suspension problems within the Gunners squad. But the 18-year-old will go under the knife on Tuesday after aggravating the injury during a substitute appearance in Sunday's 1-0 defeat to Everton at Goodison Park.Wenger said: "Walcott's season is over. He will have surgery on Tuesday. The medical advice is to do it now. "He was doing well until he damaged his shoulder, now he is only 50% of what he was before. "You can see that now. He was on for only 10 minutes and his shoulder popped out, you cannot play football like that."
