Dominic Calvert-Lewin will undergo a scan on Thursday to determine the extent of the hamstring injury he sustained in Everton's 5-4 victory over Tottenham.
The 23-year-old is a major doubt to face Fulham at the weekend after being substituted in the 55th minute of the FA Cup tie, having scored his 19th goal of the season in all competitions.
His third goal in as many games levelled things up after Spurs had taken the lead early on, before chaos ensued at Goodison Park.
Any absence will be a huge blow to Everton, with the England striker having reached the 50-goal mark for the Toffees against Spurs.
In January a hamstring injury kept Calvert-Lewin out of the cup win over Rotherham and Premier League victory at Wolves.
The second Overhaul has arrived in Sky Sports Fantasy Football - a period where players can make unlimited changes to their side until Saturday 12:30pm.
For Sky Sports Fantasy Football fanatics, it is it a week filled with optimism, hope, and an awful lot of planning, more so than the usual amount.
The second Overhaul is here, a time for change and a look into the future, as pretty much anything goes. Aside from the £100m budget remaining the same, Sky Sports Fantasy Football players can make unlimited changes to their side without them counting towards the 40 they have available for the season.
If you wanted a full team of rampant Manchester City players, you could do it, so long as you are within the £100m budget. Now is the moment to get the edge over your fierce friends in mini-leagues, earn the bragging rights, or even put yourself in contention for the £50,000 jackpot.
For many of us, that may not be a realistic possibility, but with new fixtures on the horizon and plenty of cut-throat decisions to be made, there are some players who should be at the forefront of consideration to make your final second Overhaul XI.
