The Cameroon captain Samuel Eto’o will miss Wednesday’s match against Croatia and may play no further part in the World Cup because of a knee injury, both he and team officials said on Monday.

The four-times African Footballer of the Year tweeted that he was out of the next Group A match against Croatia in Manaus.

“The doctors confirm! I would probably not be able to play the match vs Croatia … due to an injury on my knee causing me pain,” he said on his Twitter account.

“Eto’o has been told by the doctors he cannot play for the next 10 days,” said the team’s media spokesman, Laurence Fotso. If out for 10 days, it would also mean him missing Cameroon’s final group game against the hosts Brazil in Brasília next Monday. Eto’o has battled with the knee problem from the end of the English league season with Chelsea.

“For three and a half months, I have not had the time to recover. You could see that even in the buildup to the World Cup I hadn’t had a lot of practice until the friendly against Germany,” he told Cameroon state television on Sunday. “During the match against Mexico, I tried but after consulting the medical staff we realised that I needed a rest. Even in the ninth minute, I felt pain,” he said of Friday’s opening loss at the tournament to Mexico.

He played in just one of the four warm-up matches that Cameroon had before heading to Brazil but did feature in Friday’s 1-0 defeat by the Mexicans in Natal, where he spurned several chances. Eto’o also missed training at the weekend at the side’s base at Vitória.
