Everton fans are reeling today after it was confirmed that the injury suffered by John Stones was serious and the England international faced a prolonged spell on the sidelines as a consequence.
The talented former Barnsley defender has emerged as Everton's number one defender over the past month, after Phil Jagielka and Sylvain Distin both struggled to get out of the blocks in a poor start to Everton's current campaign.
But a week after winning man-of-the-match against Liverpool in the Merseyside Derby Stones fell awkwardly after going up for a header and suffered ankle ligament damage.
Roberto Martinez confirmed today that the injury will rule him out for a maximum of 14 weeks, meaning Everton fans will be waiting until 2015 to see Stones back in action.
But what does that mean in regards to the fixture list?
What big games will Stones miss?
Well, quite a few as it happens.
First of all their is the UEFA Europa League. Stones will not be available for any of the remaining Group Stage games. That means he misses the tricky double header against Ligue 1 side Lille - and their loanee Liverpool striker Divock Origi.
He will also miss the trip to Wolfsburg, where VfL will be hoping to put on a much better show than their visit to Goodison Park - where Everton mopped the floor with the Bundesliga outfit. He will also miss the visit of FK Krasnodar.
In the Premier League there is only three stand-out games on paper. He is likely to miss both Premier League games against Manchester City this season. Everton play the reigning champions on the 6th December and 10th January - Stones may make it back in time for that fixture.
He will also play no part against Tottenham Hotspur at the end of this month, as Everton's hopes of Champions League qualification continue to take hits.
Games against Southampton away and Swansea at home would also have been fixtures the club would like to have called on Stones.
He should be back in mid-January, meaning he will feature in games against Arsenal, Chelsea, Manchester United and Liverpool - but by then the damage to Everton's season could be done.
All Everton fans will be wishing him a speedy recovery.
