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.
