Malcolm Glazer, the owner of the N.F.L.’s Tampa Bay Buccaneers and the renowned English soccer club Manchester United, which he purchased in 2005, creating a furor among its fans, died on Wednesday. He was 85.

His death was announced by the Buccaneers. The team did not say where he died.

Mr. Glazer had a stroke in 2006 that impaired his speech and his mobility in his right arm. His family has represented him in running the football and soccer franchises.

The Buccaneers said Wednesday that Mr. Glazer’s wife, Linda, along with their five sons and a daughter, would continue family ownership under a long-established estate succession plan.

On a Sunday night in January 2003, Mr. Glazer accepted the N.F.L. championship trophy after his Buccaneers routed the Oakland Raiders in Super Bowl XXXVII, the climax of their stunning transformation in his eight years as their owner.
