Caitlin Clark turned a brutal double-duty night into a headline-grabbing moment off the court … linking up with Morgan Wallen during his second Indianapolis show, just hours after a gut-punch loss.

Clark had just finished a tight matchup against the Dallas Wings, where her team came up short by just three points in a game that stayed close down to the final minutes. However, instead of heading straight into a quiet postgame night, she later made her way to Wallen’s sold-out concert stop in Indianapolis.

The “I Got Better” country singer — who was in town for night two of his “Still The Problem Tour” stop — surprised the crowd when Clark walked out alongside him … sending the arena into a frenzy.

Clark, who has quickly become a face of women’s basketball and a major draw in every arena she enters, appeared in good spirits despite the earlier loss … smiling and engaging with the crowd as Wallen welcomed her onstage.
