Everton take on Middlesbrough in the Capital One Cup tomorrow evening.
Everton take on Middlesbrough in the Capital One Cup quarter-final, but they could be without their first choice midfield duo at the Riverside Stadium.
Both McCarthy and Barry picked up knocks during the Toffees’ match against Bournemouth at the weekend, and they will have scans to assess the extent of their injury problems today.
"We'll have a clearer picture today. James had to come off during the game,” Martinez said. “He overextended his upper hip muscle, a little bit higher than the groin area.
"Yesterday, he was quite sore. We'll find out a bit more today. It's exactly the same with Gareth Barry. He had a really nasty knock to the shin. There were stud marks there. He was finding it really difficult to walk yesterday.
"Those two players will have to be assessed before we name the squad."
McCarthy has damaged has hip, while Barry has picked up a knock to the shin, leaving their chances of playing limited.
The pair’s absence is a blow for Everton, as they seek to win their first trophy under Martinez’s guidance.
The Toffees have made good progress under the Spaniard’s regime, but they have a excellent chance to deliver some silverware this season.
Although Middlesbrough are a strong Championship side, Everton will still go into the fixture as the favourites to progress.
With Barry and McCarthy sidelined, it could provide the returning Tom Cleverley with the chance to start in central midfield.
Also hopeful of being involved will be Leighton Baines.
The left-back has missed the entire season so far with injury, but EPSN claim that he is likely to feature against Middlesbrough at some point.
