Everton are nervously monitoring the fitness of strikers Romelu Lukaku and Arouna Kone after they both came off with injuries during Sunday's win against QPR.
Lukaku was seen clutching his hamstring midway through the second half and although he tried to run it off, had to be substituted for Ross Barkley on 69 minutes.
The 21-year-old linked up with the Belgium squad for upcoming Euro 2016 qualifiers against Cyprus and Israel but has since been ruled out of both games by manager Marc Wilmots.
That may not be a bad thing for Everton as Lukaku now has two weeks to rest and get back up to full speed for the final few weeks of the campaign.
Kevin Mirallas is also out of the Belgian team as he continued to struggle with a dead leg picked up against Newcastle last weekend.
There is more concern though about the fitness of Kone, who has had a scan on a knee injury sustained in the build-up to Everton's winner.
Kone was tackled by Nedum Onouha at the near post and although he was back on his feet by the time Aaron Lennon had fired the ball into the net, he soon called for the physio and had to be substituted straight away.
After missing more than a year with a serious cruciate knee ligament injury the sight of Kone clutching his knee yet again is a worrying sight.
The hope is that the scans will not reveal any serious damage, as anything significant could force Kone to spend another lengthy spell on the sidelines.
