Séamus Coleman could be an injury doubt for the Republic of Ireland's crunch UEFA Euro 2020 qualifier against Slovakia next week.
The 31-year-old Killybegs man went off injured clutching his hamstring in the 58th minute during Everton's 4-2 Premier League victory over Brighton at Goodison Park on Saturday afternoon.
Coleman is set to have a scan tomorrow to assess the extent of the damage with his Everton manager Carlo Ancelotti saying that it looks like "a small issue" after the game.
It leaves the Toffees defender in a race to be fit for Thursday's qualifier with Stephen Kenny's squad set to fly out to Bratislava on Tuesday.
Today's win has kept Everton at the summit of the Premier League and Ancelotti is delighted that they've now opened with four successive victories in the English top-flight.
"We are really pleased for the start, we did really well this period, winning games, showing good quality, the spirit is good.
"But it is only the start of the season.
"Now there is the international break and we can have rest.
"It was a busy time and we have to come back with the same spirit and attitude.
"In general the attacking football was good, we had opportunities and we were really clinical on set-pieces, really good on the counterattack, we played a complete game.
"When we defended with the low block we were in a good position, we defended well and so I am pleased."
