John Stones injures ankle ligaments, extent of damage unknown

John Stones sustained an ankle injury at the end of the loss to Manchester United on Sunday. Roberto Martinez confirmed the injury during his post-match interview, saying that there was damage to the defender's ankle ligaments, but that it will take a day or two for the extent to be known.

Martinez confirms Stones has injured his ankle ligaments and will be assessed over the next 48 hours.

Stones' injury adds to Everton's lengthy list of injury woes that includes Ross Barkley, Seamus Coleman, and Kevin Mirallas.

Evertonians will hope that Stones ankle problem is not serious and that he can take the international break to recover. Stones had been demonstrating top form and had replaced the aging and struggling Sylvain Distin at center-back. He put in a strong performance on Thursday in the Europa League matchup against FC Krasnodar.
