Chelsea have been dealt a blow with the news that John Obi Mikel will miss the FA Cup final after undergoing minor knee surgery.
The 23-year-old midfielder has been out for the last three weeks following a challenge from Bolton's Kevin Davies in last month's Premier League clash.
He started the next game against Tottenham but was forced off early on after a recurrence of the problem.
Mikel will also miss the last game of the league campaign on Sunday, when a win for the Blues against Wigan at Stamford Bridge will be enough to clinch the title.
The Nigerian has started three FA Cup games this season, against Cardiff, Stoke and Aston Villa, and Michael Ballack could deputise in his place.
