Roll up! Roll up! It's time to have a go at our fiendishly difficult sporting quiz of the week.

From an Irishman playing against the Lions, to the "farce" of a potential fight between Conor McGregor and Floyd Mayweather, it's all covered in this week's quiz.

Anyway, let us know how you got on by tweeting us @NewstalkSport, and, most importantly, don't disappoint Roy Keane - he'll be dispensing the marks at the end of the quiz.
