Thomas Bjorn of Denmark was disqualified for signing an incorrect scorecard on Friday after the second round at the Genesis Scottish Open in North Berwick, Scotland.

Bjorn, 51, followed up a 5-over-par 75 on Thursday with an 8-over 78 at The Renaissance Club. The former European Ryder Cup captain, however, was listed as having signed for a 7-over 77 on Friday.

Whether Bjorn was 12- or 13-over par wouldn't have mattered. He was going to miss the cut either way.

Bjorn took to social media to share his side of things.

"First for everything. Even checked the scores as I always do .... Need (glasses emoji)," Bjorn wrote on Twitter. "Anyway, golf was awful and need to get back to the grind. Not a nice look to get dq and it's unprofessional."
