Everton manager Roberto Martinez has revealed that he expects Steven Naismith to be fit for Saturday's trip to Chelsea in the Premier League.

Naismith suffered concussion last weekend during the Toffees' 3-1 win over Swansea City in the FA Cup.

Despite early fears about the welfare of the 27-year-old, Martinez is confident that the Scot will be available for the team's visit to Stamford Bridge.

"Stevie has reacted really well. It was a little bit of a concern straight away when he had that delayed concussion," he told Everton's official website.

"Two hours after the game he was fine but for the next 24 hours it's then important you're in observation and we're checking all the signs are right.

"Over the next three or four days we're going to keep an eye on how he is recovering, but I would say that Stevie will be fully fit for the weekend because he's ready now to get back to work as normal."

Naismith has scored six goals in 23 games for Everton so far this season.
