"Matt Leinart's days in Arizona may be numbered.

The Arizona Cardinals have been calling around the league trying to trade their former first-round draft pick, FOXSports.com has learned.

Several teams have confirmed that they have received calls and e-mails from the Cardinals regarding his services, but it is not yet clear what sort of compensation that Arizona is seeking.

Leinart lost his starting quarterback job this preseason to Derek Anderson.

After his demotion to the second string, Leinart said, "I think this goes beyond the football field.

"I've done everything they've asked of me and more – outplayed the competition in training camp and preseason."

"Obviously there's something that's going on; I don't know what it is.""
