Arsenal manager, Mikel Arteta, has confirmed a double injury blow following their 1-0 win at West Ham on Sunday.
Leandro Trossard scored what proved to be the winner in the 82nd minute.
The result keeps the Gunners five points clear of Manchester City, but it came at a cost.
Ben White was taken off with a knee injury in the first half and replaced by Martin Zubimendi.
After the break, Riccardo Calafiori did not reappear with the rest and was replaced by Cristhian Mosquera.
When asked for an update on White’s condition at this post-match press conference, Arteta told reporters: “We don’t know [the severity] but it doesn’t look good at all.
“He needs some further testing tomorrow probably and I will know a bit more.”
