GLENDALE, Ariz. (AP) - Carson Palmer threw for 311 yards and Arizona returned two of Colin Kaepernick's first four passes for touchdowns and the Cardinals romped past the San Francisco 49ers 47-7 on Sunday.
Larry Fitzgerald caught nine passes for 134 yards and two touchdowns and Chris Johnson rushed for 110 yards and two scores for the Cardinals (3-0), who won at Chicago 48-23 last week.
It's the first time the franchise has had two 40-point victories in a row since 1969 and its largest margin of victory since a 44-0 win over Houston in 1970.
Kaepernick threw a career-worst four interceptions, two by Tyrann Mathieu, and finished 9 for 19 for 67 yards.
Justin Bethel returned the first one 21 yards for a touchdown and Mathieu ran untouched 33 yards for another score.
Kaepernick had a 12-yard TD run for San Francisco (1-2).
