WATCH: Joe Brolly joins wild Antrim celebrations after his son kicks two extra-time points

Like father, like son.

The Antrim minor football team produced a giant-killing in Ballybofey Sunday in seeing off their Donegal rivals against the odds after extra-time. Antrim's victory sets them up for a semi-final clash against Derry or Tyrone, in which they will be bidding to make their first Ulster Final in this grade since 2006. The sides were deadlocked at the end of normal time after playing out a pulsating encounter. https://twitter.com/CGJ1994/status/866384885241565184 That was when Ruairí Brolly stepped up to the plate to put the Saffrons in the ascendency. Ruairí, son of Joe stepped up when his county needed him most with a late brace from play. Antrim went on to win by the smallest margin possible, with Tiarnan McAteer kicking the winning score in a game which neither side deserved to lose. The Antrim players celebrated with the same vigour and energy that gave them the upper-hand during the game as can be seen here. https://twitter.com/AontroimGAA/status/866391054131634180 A visibly proud and excited father in Joe Brolly made his way onto the pitch to join in the celebrations with the Saffron's young guns. That's passion.
