Talley was an exclusive rights free agent and could only sign with the Cardinals if he was tendered an offer. DeChristopher was waived after failing a physical.
Talley has spent the last two seasons with Cardinals and appeared in nine games with one start over that span. In three games last season, Talley had eight tackles, one sack and a pass defensed.
DeChristopher was waived/injured by the Cardinals last season as well with a back issue.
