THE STORY: The Arizona Cardinals attempt to remain undefeated as they host the Miami Dolphins on Sunday. Arizona is one of only three teams with a perfect record after three weeks, joining Houston and Atlanta. The Cardinals have not begun a season with four straight victories since 1974, when they still were located in St. Louis. Miami is coming off an overtime loss at home to the New York Jets. Dan Carpenter missed a 48-yard field goal in the extra session before New York booted a 33-yarder to win. The Dolphins and Cardinals are meeting for only the 11th time, with Arizona winning the last two matchups after losing the first eight. The Cardinals rolled to a 31-10 victory on Sept. 14, 2008 in the most recent meeting.
TV: 4:05 p.m. ET, CBS. LINE: Cardinals -5.5, O/U 39.
ABOUT THE DOLPHINS (1-2): Running back Reggie Bush is questionable after suffering a sprained ligament in his left knee last week against the Jets. Bush, who underwent an MRI that revealed no structural damage, is averaging 6.0 yards per carry. Rookie quarterback Ryan Tannehill is last in the league after three weeks with a 58.3 passer rating. Defensive end Cameron Wake is two sacks away from becoming the seventh member of the Dolphins to reach the 30-sack plateau.
ABOUT THE CARDINALS (3-0): Arizona may have some reinforcement for Sunday as safety Adrian Wilson and tight end Todd Heap could return from injuries. Wilson missed last week's victory over Philadelphia with an ankle injury while Heap sat out with a bad knee. Wide receiver Larry Fitzgerald was named the NFC Offensive Player of the Week after hauling in nine passes for 114 yards and a touchdown. The Cardinals have won seven consecutive home games, two shy of the franchise record set in 1925, when the club called Chicago home.
1. The Cardinals are tied for second in the league with 12 sacks and have recorded at least two in an NFL-best nine consecutive games.
2. With 205 receiving yards, Fitzgerald will become the second player ever to surpass 10,000 yards before the age of 30, joining Randy Moss.
3. Arizona has won 10 of its last 12 games, with four triumphs coming in overtime and five more being decided by less than five points.
PREDICTION: Cardinals 27, Dolphins 17.
