Cardinals rookie CB Peterson hurts Achilles

Arizona Cardinals rookie cornerback Patrick Peterson hurt his

left Achilles tendon while making an interception Saturday and left

in the third quarter of a game against the Cincinnati Bengals.

Peterson picked off Andy Dalton’s underthrown pass and pulled up

while running. He fell to the ground and grabbed his leg. The

interception was nullified by a roughing-the-passer penalty.

Peterson, the fifth overall pick, has tied the NFL record by

returning four punts for touchdowns this season. He and Detroit’s

Jack Christiansen (1951) are the only rookies to run back four for

touchdowns.
