A Broncos contingent led by John Elway left Centennial Airport at 8:24 this morning. The Cessna is scheduled to land in the Raleigh-Durham Airport at 11:08 a.m.

Free-agent quarterback Peyton Manning has been working out at Duke University under the direction of his former University of Tennessee coach David Cutcliffe.

It's not known if the Broncos are going there to close the deal with Manning or have a second meeting or watch him work out. It's also not known if the Tennessee Titans will be making a similar trip.

All signs point to Manning narrowing his choices to the Broncos and the Tennessee Titans.

The Broncos privately have said money would not be an issue in their pursuit of Manning. Titans owner Bud Adams said he offered Manning a "contract for life" during his visit with Tennessee coaches and executives Wednesday.

Manning's first free agent visit was with the Broncos in Dove Valley on March 9. He toured the facility and met with the Broncos brass at Dove Valley until 7:15 p.m. when the group departed with a police car leading their way.

He visited Tennessee on Wednesday, and has also made trips to Arizona and Miami.

Arguably the most decorated free agent in NFL history, the long-time Indianapolis Colts quarterback was released last week amid concerns about four neck surgeries that forced him to miss the entire 2011 season, a $26 million bonus payment that was due and the team's opportunity to select highly prized quarterback Andrew Luck with the No. 1 pick in the upcoming NFL draft.

Manning, who turns 36 on March 24, has been cleared to throw by his neck specialist, Dr. Robert Watkins.
