If Peyton Manning doesn't play another down in the NFL, the Colts may not be responsible for his five-year, $90 million contract. He signed the new deal on July 31. NFL Network's Michael Lombardi reports that Manning would be eligible for termination pay in the amount of $1 million in 2012 and $500,000 in 2013 if his recent neck surgery prevents him from playing again, according to a league source. Manning's contract includes a $28 million non-guaranteed option and a separate $28 million non-exercise fee in place if Indianapolis chooses not to pick up the previous option, the source told Lombardi. According to Lombardi, terms of the deal leave a small window in which the Colts could cut Manning and not pay either sum, meaning he would earn $26.4 million in 2011. Manning underwent single anterior fusion on his neck Thursday -- his third neck operation in the past 19 months.
