Minnesota football coach Jerry Kill announced his retirement, effective immediately, Wednesday morning in a press conference.

The 54-year-old Kill went 29-29 in four and a half seasons with the Golden Gophers and finishes his coaching career with a 156-102 record.

Defensive coordinator Tracy Claeys, who has worked with Kill for the last 21 years, has been named interim head coach. Claeys filled in for Kill during his seven-game leave of absence in 2013, leading the Gophers to a 4-3 record with wins against Northwestern, Nebraska, Penn State and Indiana.

Kill signed a contract extension in August that increased his pay to $2.5 million per season. The contract includes language that plans for any health-related absences and would also allow him to ?transition? to another position in the athletic department at a substantially reduced salary.

There was plenty of Twitter reaction to Kill's retirement, and you can see it in the tweets below.
