Josh Giddey urged to 'tighten his circle' by ex-NBA star amid investigation into Oklahoma City Thunder's alleged inappropriate relationship with a minor

Andrew Bogut has implored Josh Giddey to 'tighten his circle'.

Shooting guard Giddey, 21, is the subject of an NBA investigation amid claims he had an inappropriate relationship with a minor after photos of him with a girl were recently posted on social media.

Giddey was asked about the accusation as he made his return to the basketball court on Saturday and said: 'Yeah, I mean I understand the question obviously, but, err, there's no further comment right now.'

The 21-year-old is one of the NBA's brightest stars and has earned lucrative sponsorship deals already in his young career, although Weet-Bix confirmed they are monitoring the investigation closely, with the basketballer a $40million ambassador for the cereal brand. 

And former Golden State Warriors star Bogut weighed in on the investigation on his podcast.

'It's just an absolute s***show as it is on social media. The damage has been done to his PR regardless of what the result is.

'We've had trial by media over the last 30 years and now trial by social media is probably a hundred times worse.

Bogut went on to urge Giddey to 'tighten his circle' once the dust settles.

'He's got so much to lose. Regardless of what comes out in the next week or two ... all the memes and all this s*** now, that's going to be there forever. It's hard to take it back on social media.

'It's just a s****y situation for everyone involved.

'It's a valuable lesson for Josh. He's got to tighten his circle and focus on that because he's only in this thing for 10 or 15 years.

'From what I understand and knew, he's never been a guy that's gotten in trouble or knowingly wanted to go out and be silly.'

Daily Mail Australia has contacted Giddey's management for comment.
