what to do if your kid says he doesnt like playing basketball

My son is 6 years old and begged me to sign him up for basketball, even though he knew nothing about the sport, I signed him up so he could learn, with only 3 games left in the season, & probably only 3 more practice days & him showing no interest the entire season he finally told me today before his game that he doesnt like basketball & he doesnt want to go to his game today. I feel like that would really be letting his team down, and I think he should finish out the season but I dont want to make him do something he doesnt like to do, & it’s actually embarrassing watching him pay no attention and be in a completely different world during the game. I can tell he doesnt enjoy it, but i kept taking him because each time he told me he liked it.. now that he finally addmitted he doesnt im not sure how to respond
