Samuel Eto'o has been ruled out of Cameroon's clash with Croatia due to a niggling knee injury.

The Chelsea striker has been struggling with the problem since the end of the season and hasn't trained for the past two days.

And the experienced frontman has taken to Twitter to confirm he has lost his race against time to be fit for Wednesday's clash.

He said: "The doctors confirm! I would probably not be able to play the match vs Croatia on Wed June 18th due to an injury on my knee causing me pain."
