In addition to signing defensive end John Abraham and offensive tackle Eric Winston on Thursday, the Cardinals released linebacker O'Brien Schofield and placed rookie receiver Ryan Swope on the reserve/Retired list. Linebacker Kenny Rowe was also signed.
Schofield's post-college career has been littered with bad luck: He tore his ACL during a 2010 Senior Bowl practice, then came back strong in 2011 with 4.5 sacks. He had 4.0 sacks last year before ankle surgery forced him to injured reserve.
Swope has dealt with concussion symptoms that go back to his college days since being drafted by the Cardinals in the sixth round of the 2013 NFL Draft.
