Manning and Denver Broncos Executive Vice President of Football Operations John Elway arrived in Colorado on Friday afternoon and met for six hours to discuss Manning's options.
The Denver Post reports that the team sent a plane to Miami to pick up Manning at his home while Elway, coach John Fox and general manager Brian Xanders watched Oklahoma State's pro day.
There have been numerous reports that Manning is considering the quarterback position in Denver.
It is unknown at this time how likely it is that Manning would to accept the offer, and what the Broncos would do with quarterback Tim Tebow.
9NEWS has confirmed that Manning left that facility on Friday night and spent the night in Colorado. The source told 9NEWS Manning would reassess things Saturday morning.
Elway, Xanders and Denver Broncos owner Pat Bowlen arrived at Dove Valley on Saturday morning, but there was no sign of Manning.
Manning arrived in Colorado just after 1:30 p.m. on Friday at Centennial Airport. He and Elway then went to Dove Valley.
The team says the four-time MVP was at the Broncos headquarters Friday afternoon, meeting with club officials. Elway, Manning and head coach John Fox chatted while taking a tour of the team's practice field and heading to the weight room.
Manning then went into a closed-door meeting that lasted for several hours.
The Broncos are merely one of perhaps a half-dozen - or more - clubs that are thought to be seriously interested in signing Manning, even though he turns 36 later this month and is coming off a series of neck operations. He missed all of last season, and the Colts decided to cut ties rather than pay a $28 million bonus that was due this week.
Arizona, Miami, Kansas City, Seattle, Tennessee, Washington and the New York Jets all are considered possible destinations; Manning's former offensive coordinator in Indianapolis, Tom Moore, worked for the Jets as a consultant last season.
It's not very often that teams get a chance to sign a QB who's thrown for more than 50,000 yards and nearly 400 touchdowns, has been picked for 11 Pro Bowls and been chosen as a Super Bowl MVP. Manning's importance to the Colts' success was never more apparent than last season, when their record plummeted to 2-14 without him.
Because he was released and went on the waiver wire Wednesday, Manning is allowed to negotiate and sign with any club immediately; he does not need to wait until the free-agent period that begins next Tuesday.
