Brazilian winger Raphinha sustained an apparent hamstring injury and was substituted in the 40th minute during Brazil's World Cup Group C match against Haiti on June 19 in Philadelphia.
The Barcelona forward went down while running on the right wing and was replaced by Bournemouth's Rayan.
Brazil led 2-0 at the time, thanks to two goals from Matheus Cunha.
Recurring Problem
The injury is a recurring issue for the 29-year-old, who missed five weeks of club action after damaging his right hamstring in a friendly against France on March 27.
Brazil entered the match following a 1-1 opening draw against Morocco, which drew criticism over the team's creativity and starting lineup under coach Carlo Ancelotti.
Ancelotti defended his squad selection and expressed confidence despite pressure to start 19-year-old Real Madrid forward Endrick.
"I'll bring Endrick on at the right moment. We'll have to wait a little while," Ancelotti said.
"He'll be important in this World Cup. For me personally, Endrick is an extraordinary talent.
Brazil will make the most of his qualities in this World Cup and in the next one too," he added.
Ancelotti remained calm about the draw against Morocco, where forwards Igor Thiago, Raphinha, Lucas Paqueta, and Matheus Cunha failed to score.
"The result against Morocco wasn't good but we need to offer constructive criticism," Ancelotti said.
The Brazilian squad worked to correct their performance errors before facing Haiti, who entered the match ranked 85th globally.
"You don't win the World Cup in the first match. We have to find a solution.
The players' self-criticism was positive," Ancelotti said.
The manager maintained that the team would resolve their tactical issues as the tournament progressed.
"We've been working over the last few days to sort this out and I think we will. Whether sooner or later, we'll sort it out.
I remain confident that the team will be competitive in this World Cup," he said.
Haiti's Perspective
Haiti's manager Sebastien Migne highlighted the historical significance of the fixture for his team, which had only made one prior tournament appearance in 1974.
"We've got everything to gain in a match like this.
It's been 52 years since we last featured in a World Cup, and now we're up against Brazil – we've got to live up to our fans' expectations," Migne said.
Migne expressed hope that the squad would deliver a performance to satisfy their home country.
"It's a privilege to be here and I hope we can make the Haitian people proud of us," he said.
The Haitian manager noted the massive impact a potential victory would have across his nation.
"It would be absolute madness in Haiti if we won this match," Migne said.
Brazil's next scheduled tournament appearance is a final Group C fixture against Scotland on Wednesday, a match that injured forward Neymar targets for his return from a calf problem.
