Seeing his country Cameroon go down 1-0 to Mexico was not ideal, and he has suffered an injury which rules him out of their match with Croatia tonight.
But perhaps the 33-year-old is not a great loss to the African side - not on the basis of his first game in any case.
Eto'o was named by French newspaper L'Equipe as one of the five flops of the tournament so far, described as 'invisible.'
Also listed were Pepe and Portugal, Edinson Cavani's Uruguay, Iker Casillas and Spain, and the referee in the opening match between Brazil and Croatia.
Was Eto'o really that bad? Here's a look at his opening display in their Group A loss.

Eto'o offered no goal threat for Cameroon, landing each of his two shots off target. From a creative perspective he was nowhere either, and dominated aerially.
Cameroon had promising striker Vincent Aboubakar on the bench, and it is looking like now is the time for the 22-year-old Lorient frontman to take his place and show what he can do.
Eto'o, soon to be a free agent, was linked with a summer transfer to Arsenal before the tournament, but on the basis of his first game will have done little to convince the Gunners he is worth snapping up.
