Free agent quarterback Peyton Manning has narrowed his options to the Denver Broncos and the Arizona Cardinals, according to ESPN.com.

On Saturday, Manning visited the Broncos, who have Tim Tebow under center. How is Tim Tebow handling the speculation that Manning may wind up a Bronco?

Tebow, who is expected to be traded if Manning signs with Denver, has not spoken to the media since Manning's visit and has not responded to the rumors on his official Twitter account.

Lionel Bienvenu, sports anchor for ABC's Denver affiliate, tweeted Saturday that Tebow refused to speak to reporters in Tampa, Fla., where he was meeting with wounded veterans. Bienvenu called Tebow's declining a media interview understandable.

Nicole Darin, a sports anchor for the CBS affiliate in Tampa, speculated on Twitter that Tebow was rattled by the news of Manning's visit to Denver. Darin did not get a chance to speak to the Broncos quarterback.

Manning was cut from the Indianapolis Colts last week after 11 seasons with the only team he has known since being drafted No. 1 overall in the 1998 NFL Draft. The move by the Colts makes it a virtual lock they will select phenom Andrew Luck, the quarterback out of Stanford, with the first overall pick in this year's draft.

Tebow guided the Broncos to a string of come-from-behind victories last year, which catapulted him to national prominence. His kneeling down and praying after games gave birth to the Tebowing craze that swept the country.

But while Tebow was a winner, his passing accuracy was underwhelming, instead using his running ability to overpower defenses.

Should the Broncos sign Manning, reports indicate Tebow will be traded, as it is difficult to see how the two quarterbacks can co-exist. The Jacksonville Jaguars are ideal trading partners with the Broncos since Jacksonville eyed Tebow in the 2010 NFL Draft, but Denver traded up in the draft to nab the former Florida Gator.

Manning is also reportedly intrigued by the possibility of playing with the Arizona Cardinals, who have star wide receiver Larry Fitzgerald on their roster.
