Everton midfielder Muhamed Besic has been ruled out of the team's Premier League opener against Watford through injury.
The 22-year-old picked up a hamstring problem during the Toffees' pre-season win over Swindon Town on July 11.
While claiming that Besic is recovering well, manager Roberto Martinez does not expect the 22-year-old to be fit for Everton's clash at home to Watford on August 8.
"Mo picked up the injury against Swindon and is recovering really, really well," the Spaniard told the club's official website. "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."
The Merseysiders finish their pre-season campaign on Saturday when they face Leeds United at Elland Road.
