ESPN's Chris Mortensen is reporting that 4-time MVP quarterback Peyton Manning will officially be released by the Indianapolis Colts tomorrow. Manning has spent his entire 14 year career with the Colts.

Peyton Manning has made it clear that he will continue his career in the NFL, rather than retire. The Colts, faced with the option of paying Manning a $28 million bonus this Friday or release the former Super Bowl MVP, have decided on the latter.

Before the start of last season, Manning had started every game in Indianapolis since his rookie season (pictured left as a young rookie in 1998). He missed all of the 2011 season after undergoing his 3rd neck surgery in 19 months. He's reportedly undergone 4 neck operations during his playing career.

Every single Colts passing record has been shattered by Manning during his career. He's led Indy to 11 playoff appearances, won seven AFC South titles in eight years, captured two AFC championships, and won Super Bowl XLI.

Indianapolis is expected to select Stanford QB Andrew Luck with the first pick in the upcoming NFL draft.
