Everton boss Roberto Martinez has revealed that he is unsure how long the injured Tom Cleverley will be sidelined for.
The midfielder suffered ligament damage during the team's goalless draw with Tottenham Hotspur on Saturday.
Reports have suggested that Cleverley will be missing for up to two months, but Martinez admits that he does not know when the 26-year-old will be back.
"We have mixed feelings because we feared the worst when that challenge happened," he told the club's official website. "We thought that it was a fracture and to have a fracture at this stage of the season for Tom would have been devastating because his form has been terrific.
"He has got ligament damage and the next step will be to see how long he is going to be out. It's an injury we need to try and recover as quickly as we can but clearly it's good news from when we saw Tom falling to the ground at White Hart Lane."
Everton are back in action on September 12 when they host champions Chelsea in the Premier League.
