MINNEAPOLIS (AP) Minnesota coach Jerry Kill says he is retiring because of health reasons.

Kill made the surprise announcement on Wednesday morning, one day after missing a scheduled meeting with the media. Kill has epilepsy, and had to take a leave of absence from the team in 2013 while dealing with seizures.

Kill was 156-102 in coaching career and 29-29 at Minnesota.
