Costa apparently got injured in training with Spain, was assessed immediately by their medical team and sent home. Sounds precautionary but it will now be down to Chelsea to asses the extent of the injury but indications are a thigh injury
Good news is that Costa will get at least a 2 week break assuming he is fit to play against Boro and longer if the injury is worse than thought. Plus side of that is that Michy would get to start a game (or possibly more) so we can all have a better look at him
On the Chelsea web-site it is reported that Hazard played the full 90 minutes the other day and that Courtois was rested and no mention of any injury to either player. KTBFFH
