The Cardinals released QB Matt Leinart, who failed to win the team's starting job this summer.
The 10th overall selection in the 2006, Leinart has been at the center of a difficult preseason in which he began as the starter but lost his starting spot to Derek Anderson.
"To be honest, for both parties, I think this was the best direction to go," Cardinals head coach Ken Whisenhunt said.
After expressing his displeasure, Leinart fell to second on the depth chart and completed 3-of-5 passes for 14 yards in the team's preseason finale against the Redskins.
All signs had initially pointed to Leinart replacing Kurt Warner, who retired this offseason following the Cardinals' playoff loss to the Saints.
The Cardinals explored several trade scenarios for Leinart, including discussions with the Raiders, Giants and Bills, according to various reports.
Those teams could remain interested, as well as the Seahawks, who reportedly have cut J.P. Losman and currently only have Matt Hasselbeck and Charlie Whitehurst on the roster. Leinart played at USC for new Seahawks head coach Pete Carroll.
Anderson has won the Cardinals' starting job. He was 10-5 as a starter for the Browns in 2007 and made the Pro Bowl that season but slumped badly the following season and was benched after a 3-6 mark as the starter.
Undrafted rookie Max Hall, who had an impressive preseason, reportedly will be Anderson's backup. John Shelton, another rookie, stands as the third quarterback.
