WINDERMERE — Former Tampa Bay Buccaneers star defensive tackle Warren Sapp sold his lakefront mansion outside Orlando last week for $2.9 million. Sapp bought the 10,000-square-foot Tuscan-style mansion in 2005 for $4.1 million but agreed to sell it after filing for bankruptcy in April. The five-bedroom house in the gated Reserve at Lake Butler Sound subdivision boasts a two-story wine cellar, movie theater, water slide and lazy river. The home was bought by Nebraska couple Conrad and Bonnie Muilenburg, court filings state. Sapp now works as an on-air analyst for the NFL Network. At a bankruptcy auction in November, exercise-video guru Brenda Dykgraaf posted the highest bid for the home at $2.3 million. A bankruptcy trustee rejected the bid as too low.
