Chelsea are hopeful Ashley Cole will play again this season, despite the scan on his knee confirming ligament damage.
The England international full-back was stretchered off against Blackburn on Wednesday evening, having damaged his knee when appearing to get his studs caught up in the turf.
Chelsea chief Jose Mourinho painted a negative picture in his post-match interview on Sky Sports and his fears over ligament damage have proved to be correct.
However, Cole has suffered posterior rather than anterior ligament damage and the club are hopeful he will be able to play again this season.
"Ashley Cole had a scan today on his injured knee," read a statement on the club's website.
"It was confirmed that surgery was not necessary on the posterior cruciate ligament injury and so it is expected he will play again this season."
