Neymar Jr remained on the bench as Santos lost 2-1 to rivals Corinthians in the Campeonato Paulista due to muscle discomfort.
After scoring in Santos' previous match - a 2-0 win over Bragantino - the Brazilian superstar reported discomfort in his left thigh, with this injury problem preventing him from making an appearance in his side's defeat against Corinthians.
Neither Neymar Jr himself or Santos have confirmed how long Neymar Jr will be unavailable as a result of his thigh problem.
Reports suggest it is not a serious issue, however, and Neymar is part of Brazil's international squad to face Colombia and Argentina in World Cup qualifying later this month.
