Cork duo could face sponsorship boot

The GAA and hurling sponsors Guinness could be about to launch an investigation after two Cork hurlers were seen to sport advertisements on their boots on Sunday.

Sarsfields star Kieran Murphy and Niall McCarthy, man-of-the-match in last year's All-Ireland final, both promoted drinks company Corona, a rival to Guinness, by wearing a printed ad on the toe of their Puma and adidas boots respectively, at Sunday's All-Ireland SHC quarter-final.
