France international Bacary Sagna was ruled out of next month's European Championship on Saturday after breaking his leg in Arsenal's 3-3 Premier League draw with Norwich, manager Arsene Wenger confirmed.
Sagna, 29, had only recently returned to action after suffering a fractured fibula in a game against Tottenham last October.
The defender's latest leg break occurred in the same area as his previous injury.
"It is a broken fibula, the same leg," Wenger said. "He was kicked on it, it has not happened alone. When he was kicked, he has broken the leg.
"The guy closed him down and walked on him. I don't know if it was deliberate or not."
Sagna was stretchered off during Arsenal's draw with Norwich at the Emirates Stadium on Saturday.
