Kolisi accepts he will lose Springboks captaincy
'Boks head coach Rassie Erasmus said last month he preferred his captain to be playing in South Africa, with their next Test in June.
Flanker Kolisi, 32, joined French club Racing 92, after October's second World Cup triumph, on a contract until 2026.
"That's normal. I knew that before making the decision to come here," Kolisi told reporters.
"He (Erasmus) speaks and he says this is the situation, it is what it is, there's nothing I can do about that," he added.
Kolisi will return from a thumb injury he suffered on March 2 for Sunday's last 16 Champions Cup trip to five-time winners Toulouse.
"I feel good, my hand is good," Kolisi said.
"I went to see the doctor to see the specialist and he was happy with the healing of my hand.
"I just want to be on the field. I tried to play last week but the coaches, management and doctors said I must wait for this week," he added
