I'd rather not expatiate it into a serious injury, give Anichebe or Vellios a run in.
The risk of losing Jelavic for anything longer than a few days fills me with dread. For this reason, I would not be looking to rush him back if there's any hint that he isn't 100%, so I wouldn't consider playing him against Swansea. Vic has earned his chance through a succession of goalscoring appearances off the bench. For the sake of bolstering his confidence, by showing that scoring goals gets you more game time, I would give him the start. Vellios should get a good 20 minutes too, more if Vic doesn't perform.
Stick Mirallas in the ACM role and Naismith on the right (Naismith provides better protection for Hibbert than Mirallas does), and Felli drops back to CM, allowing him to link up with Mirallas to provide an attacking platform through the middle. One of Junior, Hargreaves or Hitzlsperger to play alongside Felli; Heitinga in for Jags: Everton win 4 - 2.
