Deion Sanders -- Legendary Texas Mega-Mansion ... Up For Auction!

Wanna live like Prime Time?? Got about $10 million laying around? Then you can bid on the Texas mega-mansion once owned by Deion Sanders!

Deion's former 29,000 square-foot residence -- located in Prosper, TX -- is hitting the auction block ... just one month after the NFL legend sold the place to a real estate development company.

The house is insane -- with a movie theater, bowling alley, 10 bedrooms resort-style pool and 10 bedrooms!!!

Deion moved out of his castle in 2012 after a WAR broke out between himself and his then-wife Pilar Sanders. As we previously reported, the couple lived in the house TOGETHER even after Deion filed for divorce.

Deion has since moved into a sick $5 million condo in Dallas.
