The Colts and Peyton Manning will part ways after 14 seasons and one Super Bowl win. The announcement will come at a press conference in Indianapolis on Wednesday, according to sources. The decision to pass on the $28 million bonus owed to Manning and not to pick up the four remaining years on his contract means Manning will become a free agent. Several sources have told ESPN during the past month that Manning's throwing strength has dramatically improved as his nerves continue to regenerate. The Dolphins have recently emerged as the most likely destination for Manning.
