Cardinals' Corey Peters out for season with torn Achilles

Arizona Cardinals nose tackle Corey Peters will miss the 2015 season after tearing his Achilles.

Peters tore his Achilles in Week 16 of last season. It's unclear if he injured the same leg.

Peters spent the first five seasons of his career with the Atlanta Falcons, recording 146 tackles and 11 sacks over that stretch. He signed a three-year, $10.5-million deal with the Cardinals in March.

Rodney Gunter will replace Peters in the Cardinals' starting lineup.
