Devlin plans to sign with the Miami Dolphins instead, ESPN's John Clayton reports.
Devlin wouldn't have gotten a long look with the Cardinals, in my view. Arizona will likely add a veteran starter -- Kevin Kolb, anyone? -- this week. John Skelton remains in play as a potential future starter for the Cardinals. He looks like a strong candidate for the No. 2 job this season. Richard Bartel and Max Hall are also both on the roster. Skelton, Bartel and Hall are eligible to practice with the team before the league year begins Aug. 4.
I haven't followed the backup quarterback situation with the Dolphins as closely, but Devlin could have had a hard time making an impact in Arizona.
