Paris Saint-Germain forward Neymar has hobbled out of training with Brazil three days before their World Cup Group E clash with Costa Rica.
The world's most expensive player was absent from Monday's session as he was still feeling the effects from the Selecao's physical battle against Switzerland.
Neymar was fouled 10 times in his side's 1-1 draw at the weekend - his first competitive outing since damaging his ankle for PSG in February - to set a record from the past 20 years.
Having only lasted 10 minutes during Tuesday's training session at the Yug Sport Stadium, the 26-year-old is now considered a fitness doubt for the meeting with Costa Rica.
However, reports in his homeland suggest that the Brazil medical department are confident that Neymar will be back involved on Wednesday.
