According to Barrows, Haggans will take a physical on Sunday and, if everything checks out, will be signed to the 53-man roster.
A fifth-round draft pick out of Colorado State by the Steelers in 2000, Haggans has been a full-time starter in seven of his last eight seasons, totaling 46.5 sacks, including three last season with the Cardinals, who had signed the 6-foot-4, 243 pounder in 2008.
The Cardinals re-signed Haggans to a one-year contract in June to provide veteran depth behind projected starters O'Brien Schofield and Sam Acho, but released the veteran as part of their cuts down to a 53-man roster Friday.
Haggans, 35, can still play. According to official playing-time documents, Haggans logged nearly 75 percent of the Cardinals' defensive snaps last season and, according to the Football Outsiders Almanac, had 15 hurries.Follow Brian McIntyre on Twitter @brian_mcintyre.
