Extra tickets have been made available for the April 28 HBO rematch between light heavyweight world champion Bernard Hopkins and Chad Dawson. The fight is being held at Boardwalk Hall in Atlantic City.

"The response for tickets to this fight has been overwhelming and I can understand why," said Richard Schaefer of Golden Boy Promotions, Hopkins' promoter. "Hopkins' and Dawson's deep disdain for one another is very intense and I have no doubt they will show it in the ring."

Schaefer also believes the HBO co-feature between Seth "Mayhem" Mitchell and Philadelphia native Chazz Witherspoon has driven interest.

"The opportunity to see two American heavyweights, who are also college graduates, face one another is rare and very exciting. We're pleased to give more fans the chance to see this extraordinary event live."

"The fact that they are opening so many extra tickets speaks volumes about the interest and excitement about this fight," said Dawson's promoter Gary Shaw. "I know Chad is ready and his fans will be behind him 100 percent."

Tickets are priced from $25 to $300 and are available via Ticketmaster or at the Boardwalk Hall box office.
