Alan Shearer and Robbie Savage kick off epic 5-a-side football match for Sport Relief

Today footy legends Alan Shearer and Robbie Savage kicked-off (literally) a 57-hour-long, 5-a-side game to raise money for Sport Relief.

By the end more than 1,000 players will have taken part in the BBC 5 Live vs Match of the Day grudge match, playing the equivalent of a whole Premier League season for one club.

The match is taking place outside BBC MediaCityUK in Salford, and started at 9:15am this morning, with the final whistle set to blow on Saturday at 6:15pm.

Shearer is captaining the Match of the Day team while ex-Wales player Savage leads the radio squad.

It's the second time they've competed for the charity; two years ago the pair raced to be the first to sit on all 90,000 seats in Wembley Stadium. That time Shearer was victorious.

Things started off nice and gently...
