Watch: RTE pundit almost drops an f-bomb as his phone starts ringing live on-air

Put it silent, Jerry.

Jerry Kiernan is always available for a phone call, even when he's on punditry duty for RTE. The former long-distance runner was in the RTE studios for their Olympic coverage ahead of the men's 100m final, and Ciara Mageean's 1500m semi-final. Kiernan, who is the Irish runner's coach, was speaking about her chances in the race, when his mobile phone started ringing. Luckily for Jerry, he didn't drop any f-bombs, despite appearing to come very, very close. https://twitter.com/SportsJOEdotie/status/764969959202000896 Exclusive interview with Paraic Duffy on the latest GAA Hour. Subscribe here on iTunes.
