Paddy Power have been forced to suspend betting on who Sky Sports will choose to be their main anchor on their GAA coverage.
It was reported last week that the GAA is in "advanced negotiations" with Sky Sports for a landmark deal to broadcast some of their games.
The bookmakers have today closed betting in its North Dublin shops because of a string of large bets on Rachael Wyse for the job.
The bookie had installed the Dubliner as its Evens favourite when it opened the betting on Friday, but were forced to slash her odds into 1/10 before pulling the plug following relentless backing yesterday.
A spokesperson for Paddy Power said: "This looks to be the mother of all one horse races in the eyes of our bettors as we’ve taken over €1,500 on Wyse and not a bean elsewhere.
"Punters seemed to be willing to back her at any price and we’re definitely running scared on this one."
