Coming off their divisional road win over the 49ers, the Cardinals played their Week 2 home opener against the Miami Dolphins. In the first quarter, the Cardinals scored first as QB Kurt Warner threw 2 touchdown passes (a 79-yarder and a three-yarder) to WR Anquan Boldin. In the second quarter, Arizona increased their lead with a 45-yard field goal by Neil Rackers. In the third quarter, the Cardinals increased its lead to 24-0 with rookie running back Tim Hightower getting a one-yard touchdown run. In the process, he became the first Cardinals rookie running back to ever score in each of his first two games. The Dolphins finally got on the board when kicker Dan Carpenter nailed a 32-yard field goal. The Cardinals replied with Warner and Boldin hooking up with each other for a third time on an eight-yard touchdown pass. In the fourth quarter, Miami tried to rally as running backRonnie Brown got a one-yard TD run, but Arizona held on for a dominating win. With the win, the Cardinals improved to its first 2-0 start since 1991. This game was also one of three times that Kurt Warner finished a game with a perfect passer rating.
