Cardinals expected to part ways with cornerback Sean Murphy-Bunting

Arizona is expected to release cornerback Sean Murphy-Bunting, a move that would close out his time with the Cardinals and reshuffle the team’s cornerback group for the 2026 season.

Murphy-Bunting missed all of last season due to injury, and although he agreed to a revised contract for 2026, Pro Football Rumors reports that he is no longer in Arizona’s plans. If confirmed, the decision marks an end to his tenure in the desert, which the report characterizes as including only one season.

The Cardinals’ decision, as framed by the report, is less about a single on-field moment and more about roster construction after a lost year. For an NFL team, a full-season absence typically forces evaluation of readiness and role fit, particularly for positions like cornerback where timing with the defensive scheme and communication with the secondary can be critical.

This kind of release also changes the Cardinals’ immediate options in the secondary. With Murphy-Bunting potentially removed from the active group, Arizona would need to distribute snaps and reps among the remaining cornerbacks and any additions made through depth signings, practice-squad promotion decisions, or the draft cycle.

The report does not provide specific details about the financial terms, but it does describe a revised contract for 2026 that has now been overtaken by the team’s broader roster direction. In practice, a revised deal followed by a release often indicates a shift from a “bridge” plan to a “reset,” whether that reset is driven by health, performance expectations, or the emergence of other players in the rotation.

For fans and evaluators, the immediate question becomes who steps into the responsibility Murphy-Bunting would leave behind. The Cardinals will likely be judged, at least early in training camp and the preseason look, on how quickly their secondary stabilizes after the uncertainty surrounding an offseason roster change.

Going forward, the key development to watch is whether the release is officially announced by the Cardinals and how Arizona’s secondary depth chart is finalized once Murphy-Bunting is off the roster. Until then, the report should be treated as an expectation rather than confirmation.
