Chelsea were forced to settle for 0-0 draw against Blackburn after a second half 'goal' was controversially ruled out by referee Howard Webb.
The Blues looked to have sealed all three points when Salomon Kalou converted a cross from Julian Belletti, but Webb disallowed the goal for offside.
Jose Mourinho's men had squandered a host of first-half chances but Rovers could have stolen the points themselves if Petr Cech had not tipped Robbie Savage's late effort over the crossbar.
But the visitors' point was overshadowed by a serious head injury to defender Christopher Samba, who was caught accidentally by Andriy Shevchenko's boot when he stooped to clear a header.
The hosts had been the more adventurous in the first period and were denied by a flying save from Brad Friedel, who pushed Michael Essien's fierce drive round the post.
