Everton have refused to rule out the possibility of ending their loan striker's deal early.
Roberto Martinez has admitted that Everton could terminate Lacina Traore's loan deal with the club due to his injury concerns.
The Ivory Coast international was forced to withdraw from the starting line-up for last weekend's defeat at Chelsea after suffering a hamstring injury in the Stamford Bridge warm-up.
That injury is set to rule Traore for up to a month but current indications suggest the 23-year-old could be sidelined for longer, which has prompted Martinez to refuse to rule out ending Everton's agreement with Monaco prematurely.
"It will depend on the length of time that he needs to recover," he told his pre-match press conference.
"We're going to find out over the next couple of days what's the treatment route that we're going to go down. The relationship with Monaco is very good and you get to a point where you want the best for the player.
"We need to make sure he gets the right treatment and then depending how long that's going to be. If it's only a matter of three or four weeks, we want Lacina to be here until the end.
"If it's going to be anything longer than two or three months, clearly the loan period is over. The only thing we are focusing on now is that Lacina gets the right treatment to perform in the manner that he showed against Swansea."
