Cardinals sign safety Lewis, re-sign 2 others

Posted: Updated:

TEMPE, Ariz. (AP) -- The Arizona Cardinals have signed free agent safety Keith Lewis to a two-year contract.

The team also announced Monday it had re-signed punter Ben Graham to a two-year contract and backup quarterback Brian St. Pierre to a one-year deal. Terms weren't disclosed.

Lewis was waived by San Francisco last month. A sixth-round draft pick out of Oregon in 2004, he played mostly on special teams for the 49ers.

The Australian Graham signed with the Cardinals last Dec. 1. In eight games with Arizona, Graham averaged 40.4 yards per kick.

St. Pierre was the Cardinals' third quarterback, coming to Arizona from Pittsburgh in 2006.
