Luis Suarez says his rehabilitation from knee surgery is going well, with the Uruguay striker on course to feature in the Group D clash with England.
After an incredible season with Liverpool, there had been fears whether the 27-year-old would be fit for the tournament in Brazil.
Images of Suarez being carted around in a wheelchair after undergoing keyhole surgery were broadcast around the world last month, raising concerns over his World Cup participation.
However, the forward has moved to allay fears in his homeland and, while Saturday's Group D opener with Costa Rica may be too soon, looks likely to be available when Uruguay take on England in Sao Paulo on June 19.
"Hello to everyone, I wanted to tell you that my knee is getting better," Suarez said in an 888poker video, which looked to have been filmed on the team's flight to Belo Horizonte.
"I feel very good, I have to go day by day, but everything is on the right way.
"I wanted to thank you all for the support I received during this week and now my mind is focused on the World Cup."
