The Arizona Cardinals released starting cornerback Tramaine Brock Sr. and reserve running back Zach Zenner on Monday.
Brock, 31, played in 10 games this season and made his seventh start in Sunday's 34-7 loss to the Los Angeles Rams. He tallied 37 tackles and three passes defensed, including a season-high eight tackles on Sunday.
Brock spent seven seasons with the San Francisco 49ers (2010-16) and one each with the Minnesota Vikings (2017) and Denver Broncos (2018) before signing a one-year deal with Arizona in April. He has 249 tackles and 11 interceptions in 113 career games, including 52 starts.
Zenner, 28, played in three games with the Cardinals after signing with the team on Oct. 23 following injuries to running backs David Johnson and D.J. Foster. He rushed two times for minus-3 yards with Arizona.
Zenner appeared in one game with the New Orleans Saints this season after spending his first four NFL seasons with the Detroit Lions (2015-18). His career totals include 683 rushing yards and eight scores plus 29 catches for 282 yards in 40 games (six starts).
