The Denver Broncos reportedly gained some salary cap flexibility over the next two years from the alterations made to quarterback Peyton Manning's contract last week.

The Broncos requested the change to insure themselves against having to pay Manning's $20 million salary in 2014 in the event he can't play because of a non-neck injury that might be suffered this season.

The new contract doesn't change Manning's pay and is not a restructured deal in the traditional sense, but the league's treatment of Manning's contract does change, Yahoo! Sports reported.

The contract Manning originally signed in 2012 included a $20 million salary for 2013 and 2014. Under the new deal, Manning gets a $10 million salary advance in exchange for his base salaries in 2013 and 2014 being lowered to $15 million each season.
