The NBA is doing its due diligence amid disturbing allegations surrounding Oklahoma City Thunder player Josh Giddey -- the league just announced it is "looking into" claims he had an inappropriate relationship with a minor.
TMZ Sports has confirmed the Association is aware of the rumors that have spread on social media this week ... with photos and videos alluding to Giddey being intimate with a high school girl.
Giddey was asked about the speculation at Thunder practice on Friday ... and he remained tight-lipped.
"I understand the question, obviously, but no further comment right now," Giddey said.
