Of this group, the 49ers signed Lucas to their practice squad.
Miller, 23, is a former sixth-round pick of the Cardinals back in 2016. He was waived at the start of the 2016 season and has been on and off of their practice squad the past two years.
Arizona elected to cut Miller loose shortly after this year’s draft and re-signed him during the preseason. However, he was among the team’s final roster cuts.
In 2017, Miller appeared in five games and recorded six tackles and a fumble recovery.
