Everton will be without Muhamed Besic for the start of the Premier League campaign.
But the Bosnian will be back soon after that, with Aiden McGeady and Darron Gibson also in with a chance of returning by the end of August.
Manager Roberto Martinez told evertontv: “Mo picked up the injury against Swindon in the first game and is recovering really, really well. He is a player with a lot of power and a player who I expect to be fit just after the start of the campaign. I think he will miss the opening game but after that he will be close to a return.”
Aiden McGeady has not featured in Everton’s pre-season campaign at all but he too is progressing well as the Club’s medical team tackle a persistent hamstring problem.
Martinez continued: “Aiden was carrying the little hamstring problem that affected him from the international game and he’s been carrying that niggle for a while. He has had a good week while we’ve been in Scotland and he’s getting to the root of the problem.
“We are quite confident that in the next two to three weeks he will show a good reaction to the treatment he’s been having.
“Those players, plus Darron Gibson have progressed well and I think they will be there or thereabouts by the end of August.”
Tony Hibbert has also been missing since the Arsenal game with a knee injury.
"Tony picked up a little bit of a knock against Arsenal in the Asia Trophy,” continued the Blues boss. “He has been assessed and he’s developing well. He will be out a little bit longer, I think we will have a better idea once the start of the season gets under way - probably Tony will be out for a few weeks still.”
