Club sponsor wonga.com is launching their brand new half-time competition at this Saturday's Premier League home fixture with West Ham United.

One lucky Magpies fan will go head-to-head with a Hammers supporter, racing across the St. James' Park pitch in giant inflatable zorbs for the chance to win £250.

For your chance to take part on Saturday, visit http://www.wongafootball.com/nufc/competitions and enter your details on the right-hand side. The lucky fan will be chosen in the days leading up to the match.

The competition closes at noon on Thursday (22nd August).
