Isidora, 26, is a former fifth-round pick of the Vikings back in 2017. He was in the second year of his four-year, $2.6 million contract when Minnesota traded him to the Dolphins last year.
However, Isidora was later waived at the start of the 2020 season and signed to the Chiefs’ practice squad. He bounced on and off their taxi squad until the Steelers signed him in December.
For his career, Isidora has appeared in 25 games for the Vikings, Dolphins, and Chiefs, while making five starts.
