Arsenal's Gibbs suffers broken foot
The England U21 international sustained the injury in the dying stages of the Gunners' 2-0 Champions League win over Standard Liege on Tuesday night as he returned from a foot injury he picked up on international duty last week.
"Gibbs has a big hole in his leg," Gunners boss Arsene Wenger confirmed on the club's official website.
"It was a very bad challenge by the No 22 and it was not his first try, unfortunately. It doesn't look good for Gibbs."
