WATCH: How on earth did Michael Darragh MacAuley escape a black card against Mayo?

16 minutes gone, Dublin unable to get any of their players on the scoreboard - it took them 34 in fairness - and their midfielder should be sent to the stand.

Lee Keegan goes charging upfield, he's in behind a number of sky blue jerseys until Michael Darragh MacAuley dives from behind and clips the Mayo man's heels. Keegan goes down, the ref blows for a foul, and then that's it. No card, no telling off, and no real explanation then for why Conor Lane blew his whistle in the first place. Either he saw the clip on the heels and that's why he blew it so he should've given a black card too. Or he saw nothing. If he was blowing for a free, he saw with both of his eyes that it should've been a black card. MacAuley is in no position to even think about tackling Keegan. He tries anyway. https://twitter.com/TheSundayGame/status/777520214896279554 He brings both of them to the ground and ends the Mayo attack. Conor Lane gives the free kick and isn't interested anymore and Gaels everywhere rolled their eyes once more at this confusion that is the black card - or at least its application. https://twitter.com/TadhgOgMurphy/status/777522675388481540 https://twitter.com/ianmolloy001/status/777522430113878017 https://twitter.com/seanyseo/status/777521743674089473 https://twitter.com/JeffEAbbott/status/777520211629047809 https://twitter.com/edderovers/status/777520191479611392 https://twitter.com/Hinph6/status/777520176925437952 https://twitter.com/conorjdonnelly/status/777520007450398721 https://twitter.com/Mactweets1/status/777520090636029952 The officials did seem to get the James McCarthy decision correct later in the first half when the half back was black carded - not that it made anyone feel any happier. https://twitter.com/TheSundayGame/status/777522400569155584
