The Arizona Cardinals will release quarterback Matt Leinart, a league source told ESPN NFL Insider Adam Schefter.
Leinart went in to the offseason as the heir apparent to Kurt Warner as quarterback of the pass-happy Cardinals but was unable to distinguish himself from free agent acquisition Derek Anderson in the eyes of head coach Ken Whisenhunt.
Earlier in the week, Arizona was seeking to trade the former first round pick with the Buffalo Bills, Oakland Raiders and New York Giants having been involved in discussions, league sources told Schefter on Wednesday. Instead, the Cardinals look to move away from their top selection in the 2006 draft.
Leinart bristled at the brewing quarterback controversy this preseason.
"I don't really know what else I could possibly do," Leinart said Monday. "It probably goes beyond football, beyond the field actually. For me, I am not making excuses. I am not going to complain. For me, I just really want an explanation and I haven't been given one."
On Tuesday, Whisenhunt sat down with Leinart with the coach describing the conversation as "a good talk."
With Leinart out of Arizona, the Cardinals look to a pair of rookies -- Max Hall and John Skelton -- to back up Anderson.
