Pat Bowlen has given up control of the Denver Broncos as he battles Alzheimer's disease.

"In recent years, Denver Broncos owner Pat Bowlen has taken a reduced role with his team while courageously and privately battling Alzheimer's disease," the team said in a statement.

"The Broncos are very saddened that Mr. Bowlen is no longer able to be part of the team's daily operations due to his condition. We continue to offer our full support, compassion and respect to 'Mr. B,' who has faced Alzheimer's disease with such dignity and strength."

Bowlen purchased the Broncos in 1984 from Edgar Kaiser. In Bowlen's 30 years as owner, the Broncos reached six Super Bowls, winning back-to-back titles in 1997 and 1998.
