What happened: Arizona signed safeties Hudson Clark and Devyn Bobby while cutting tight end Baylor Cupp and wide receiver Bryson Green. Trey Benson was waived with an injury designation.
Why it matters: The safety additions arrive as Arizona trims toward its 53-man roster, while the three offensive departures narrow the competition at running back, receiver and tight end. Sweat's activation makes the pass rusher eligible to practice and avoids a move to reserve/PUP.
By the numbers: The Cardinals announced seven transactions: one activation, two signings, two cuts, one IR placement and one waived/injured move.
What to watch: Final cuts will determine whether Clark and Bobby remain in the safety rotation.
