Arsenal Vilbach's attacker goes on to the right ankle surgery
Arsenal striker Danny Welbeck had another surgery in the right wrist, which was interrupted.
England striker Velbeck was injured during a match against Arsenal against Sporting Lisbon on Thursday in the UEFA Champions League. He passed the operation the next day.
"Two cases have been done well without complications," the club said in a statement released on Monday night.
"Danny will begin the recovery and start a rehabilitation program, but it is too early to predict the length of his absence."
Velbeck scored five goals this season in 14 games and was on the England's list for the next two games against the United States and Croatia.
