Neymar has returned to training with Brazil after limping out of Tuesday's session with an ankle injury.
The Paris Saint-Germain forward missed Monday's training session with the Selecao, the day after being fouled 10 times during the 1-1 draw with Switzerland in Group E.
Neymar then emerged for Tuesday's workout but only lasted a few minutes before having to come off the field.
Wednesday's session, meanwhile, was closed to the media but the Brazilian football federation stated that the 26-year-old "participated normally in the team's activity".
Neymar, who was sidelined for around three months earlier this year because of a foot injury, is now expected to be fit for Friday's meeting with Costa Rica.
