Champion fighter Mike Tyson is giving fans the chance to sit ringside with him at the year's (12) biggest boxing match to raise funds for charity.

The star is auctioning off a seat at the Manny Pacquiao vs. Juan Manuel Marquez Iv fight in Las Vegas on 8 December (12) at the city's MGM Grand Garden Arena.

The money raised from the sale will go towards the former boxer's Mike Tyson Cares foundation, which offers support and financial help to kids from broken homes.

Taking to his Twitter.com account to announce the one-off auction, he writes, "Who wants to attend the Pacquiao/Marquez fight with me and sit ringside? Go to http://charitybuzz.com to bid on this amazing opportunity!!"
