Dysert was released by the Cardinals on Friday, Darren Urban of the team's official site reports.
Dysert spent most of the 2016 season on the Cardinals' practice squad before being elevated to the 53-man roster in December. He was re-signed as an exclusive-rights free agent in March, but Arizona later brought in Blaine Gabbert and Trevor Knight to join the quarterbacks room as well. After a month of side-by-side evaluation between the three quarterbacks alongside incumbent No. 2 QB Drew Stanton, it seems Arizona management honed in on Dysert as the odd man out in an effort to begin trimming the roster down to the required 90 players.
