Chelsea midfielder Michael Essien has suffered a potentially serious knee injury in training.
The club confirmed on Friday that the Ghanaian had damaged his knee,
but stopped short of commenting on its severity, instead stating that
they will await for Essien to be assessed.
Essien suffered an injury to his right knee during training this week," read a statement on the club's official website.
"He will undergo tests over the next few days to determine the extent of
that injury. Until we have the full results of those tests we will not
be commenting further."
Essien damaged his anterior cruciate ligament while on international
duty in September 2008, ruling him out until March 2009, while he also
missed the 2010 World Cup through injury.
