Wide receiver Marquis Bundy, shown making a catch at rookie minicamp, was one of three additions Thursday.
The Cardinals returned to the 90-man roster limit by signing three players on Thursday.
Safety Tyrequek Zimmerman was brought back after a stint with the team earlier this offseason, while wide receiver Marquis Bundy and guard Jake Bernstein were also added to the fold.
Zimmerman was signed to a futures contract by the Cardinals on Jan. 5 before getting released on May 4 following a glut of undrafted rookie free agent signings.
Bundy participated in rookie minicamp as a tryout player last month. He is from Anthem and played at Boulder Creek High School before heading to New Mexico for college. Bernstein is an undrafted free agent out of Vanderbilt.
The Cardinals had three open spots after waiving guard Edawn Coughman, safety Brandon Person and wide receiver Jeff King on Wednesday.
