Chelsea midfielder Michael Essien has picked up a knee injury in pre-season training, and will undergo scans to determine the severity of the knock.
Stamford Bridge medical staff are concerned that the Ghanian may have suffered a relapse of past ailments that have blighted his career; the 28-year-old has had two long spells on the sidelines due to anterior cruciate and medial knee ligament injuries over the last three seasons.
Despite this, the London club will not panic, or further discuss the situation, until the full extent is revealed by scans.
“Michael Essien suffered an injury to his right knee during training this week. 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,” a club statement read.
The 2010/11 Premier League runners up start pre-season fixtures with a game against Portsmouth next Saturday, before travelling to Asia for a number of friendlies- the former Lyon midfielder is a doubt for inclusion in both.
