Source: Todd Grantham to Louisville

— -- Georgia defensive coordinator Todd Grantham will leave the Bulldogs to take the same position at Louisville, according to a source.

Grantham will receive a five-year guaranteed contract worth $1 million per year, the source said.

Grantham was defensive coordinator at Georgia for four seasons, installing a 3-4 scheme that led to increased sacks and takeaways. 

He previously coached in the NFL with Dallas, Cleveland, Houston and Indianapolis and previously in college at Michigan State and Virginia Tech.

Among the coaches Grantham has worked with are Frank Beamer, Bud Foster, Nick Saban, Romeo Crennel, Dom Capers and Wade Phillips. In 2011, the Georgia defense finished fifth nationally in total defense.

Louisville this week hired Bobby Petrino as head coach entering the Cardinals' first season in the ACC.

A source told ESPN's Brett McMurphy last week that Kevin Steele, who spent last season as Alabama's director of player personnel, would join Petrino's staff as coordinator. Multiple news outlets later reported Steele turned down an offer for the position.

Former UAB coach Garrick McGee, who served as Petrino's offensive coordinator at Arkansas, will join Petrino's staff to run the offense at Louisville.
