He was sent off in his debut for Scotland vs Netherlands in 1959 for lashing out I retaliation. He became the first Scotland player ever to be sent off. I believe this indiscipline partly led to his departure from Celtic.
It was a different game back then. The abuse flair players took back then was incredible. Bertie could dish it back out though. He broke the legs of Davie Provan of Rangers then George Miller of Hearts in consecutive games.
When he signed for Birmingham he was sent off for head butting Johnny Haynes and then knocked out the Fulham centre half who came to remonstrate with Bertie with one punch.
