ALI COMPOUND FOR SALE: Muhammad Ali's former training camp in Deer Lake, Pa., is headed for an online auction.

The 18-building complex in rural Schuylkill County is set to go on sale Monday on eBay and will be up for bid for 30 days, said George Dillman, a former Ali sparring partner who bought the camp from him 10 years ago.

Ali opened the camp in 1972 when he was trying to rebound from a loss to Joe Frazier in the "Fight of the Century." After building the log cabin-style gym, Ali built cabins for his wife, parents and sparring partners, as well as a mosque for daily worship.
