Constantin Ritzmann (born December 20, 1979) is a German-born player of American football.
He was born in Freiburg, Germany. He moved from Berlin, Germany to Tallahassee, Florida in hopes of achieving success in American football. As a high school senior he was offered a scholarship from multiple D1 football powerhouses, including the University of Florida, Florida State, Alabama, Tennessee, Ohio State and many more.
He ended up choosing Tennessee over Florida State in 1998.
At Tennessee, he saw playing time as a true freshman. He became a starter midway through his junior season and a team captain as a senior in 2003. He led the Tennessee Volunteers to an upset victory over then number 4 Miami which ended the nation's longest home winning streak.
During the 2005 season he was activated by the Atlanta Falcons and played in the loss to the Tampa Bay Buccaneers. His playing time in this game made him the second European non-kicking player (after Norwegian Leif Olve Dolonen Larsen) to actually see playing time during the regular season.
