Some golfers hit their ball into a sand trap during the course of a round. Allan apparently flipped his golf cart into a unker, the San Antonio Express-News reported.

"Maybe too much to drink on the course today," Allan wrote on Instagram, captioning a photo of himself with his arms raised to the sky in frustration as he looks over his overturned golf cart at the TPC San Antonio course.

Allan was in southern Texas for a concert at John T. Floore's Country store in San Antonio, the Express-News reported.

Allan included a few hashtags, including #daydrunk, the newspaper reported.
