Neymar does not feel his latest injury is anything to be overly worried about.
The Brazilian star had to be substituted off late on in Al-Hilal's 3-0 win over Esteghlal in the AFC Champions League Elite on Monday.
Aleksandar Mitrovic's hat-trick propelled Saudi Pro League giants Al-Hilal to a comfortable win, though it was soured when Neymar clutched his right thigh and left the field just 29 minutes after coming on as a second-half substitute.
It was only the 32-year-old's second appearance since he returned from a year-long lay-off due to a serious knee injury.
However, the former Paris Saint-Germain and Barcelona attacker allayed fears over a serious injury.
"It felt like a cramp, only very strong!" Neymar posted on Instagram. "I'm going to have some tests and I hope it's nothing too serious.
"It's normal for this to happen after a year, the doctors had already warned me, so I have to be careful and play more minutes."
Neymar has played only seven games for Saudi Arabia's Al-Hilal since joining from PSG in a blockbuster transfer last year.
