ANSWER:

No, it’s not permissible to play with such people whose awrah is exposed.

QUESTION: I want to play on a male sports team (I am a male too, and my awrah is covered) but some players play with shorts above their knees and sometimes when they are moving their shorts may move up and their thighs can be seen, but this might happen (not 100%) and I may or may not see their thigh at that moment. Is it permissible to play on this sports team where I might play against players like this?
