I have it in mind that it was a Barnet player in a 0-0 draw in January 1994, but I may be way out. However, I just Googled it looking for more info and Nathan Blake mentioned in one of his Echo columns that he was in the City team when Garry Thompson broke somebody's leg and he struggled to play for the rest of the game after seeing the extent of the injury. Blake was in the side against Barnet - one of the last games he played for City - so that adds up.
