Cap On At The Goalpost©©.. Big Question: Match On or Match Break?????

Hello steemians footballers!!!

Hope you noticed this, those who watched Man U vs Burnley Match yesterday.
I was astounded when I saw Dean Henderson, Man U goalkeeper putting on cap during second half of the match. I asked someone beside me, what for? He equally said he did not know.
It was later that the commentator made it clear that, it was as a result of the ☀ reflecting towards his direction.
