I jumped up in the air while playing basketball and I heard a pop. I can bear weight on my knee but not bend it. I don't think I have any symptoms of a torn acl or anything like that?

Straighten out. The fact that you cannot bend your knee after hearing a pop, is something that you might want to have evaluated. and right soon. Torn tissue jamming the joint is a consideration. An orthopedic surgeon is your best bet.
Need investigation. You have symptoms " not dent it " Possible to have injury to meniscus , or collateral ligaments , see an orthopedic surgeon for examination and possible MRI.
