Well this is interesting, and possibly very very bad. Brazilian centre half David Luiz has just tweeted a message strongly implying he won't be featuring during Chelsea's visit to Craven Cottage:

David Luiz wins the prize for 'most enthusiastic delivery of bad news ever', incidentially. Anyway, it's not entirely clear what this means for Chelsea - if John Terry isn't fit, the centre back pairing is Gary Cahill and Branislav Ivanovic and the right back is Jose Bosingwa or Paulo Fereira. Obviously that would be pretty unfortunate. Then again, Chelsea presumably wouldn't 'rest' David Luiz if he's able to play unless in so doing they wouldn't be shooting themselves in the foot, which may mean that Terry is fit despite his two cracked ribs. Of course, the other option is that David Luiz is badly hurt enough that he can't play no matter what, which :(

So this will be fun. Brace yourselves for the official lineups coming out in a few hours...
