It’s not every day one gets to interview a football legend like Vince Young, so when a Golf Channel reporter saw her chance, she took it … but there was just one problem — it wasn’t him!

The cringeworthy confusion all went down on Thursday at the BMW Charity Pro-Am in South Carolina … when Lauren Withrow thought she had grabbed VY out on the course — but instead, nabbed an assistant football coach.

Check out the video, she confidently spoke to him as if he were the former Univ. of Texas superstar quarterback … and asked him about his golf game.

The man she was actually talking to, though, was Citadel assistant Everette Sands … who tried like hell to get her out of the mess — but Withrow continued to press onward nonetheless.

To his credit, Sands — who was decked out in Citadel gear — handled the situation as well as one could despite the awkwardness of it all … answering her question well.

The interview mercifully ended after a few moments … and later, Withrow addressed the situation on her Instagram and made it clear she was hoping to learn from her mistake going forward.

While it is a pretty brutal flub … a silver lining for the reporter is that Young is, indeed, participating in the tournament. So there’s still a chance she can get him on the mic Friday … although hopefully after at least one double take.
