The Cardinals had one open spot on their 90-man roster when the day began Monday.
By the afternoon, they filled it with the signing of veteran wide receiver Michael Crabtree, according to a report by ProFootballTalk.
Crabtree, 31, appeared in all 16 games last season for the Ravens, finishing with 54 catches for 607 yards and three touchdowns.
A first-round pick out of Texas Tech in 2009, he spent his first six NFL seasons with the San Francisco 49ers and three more after that with the Oakland Raiders.
