Inside linebacker Gabe Martin, here blocking a punt in college for Bowling Green, is one of 14 undrafted rookie free agents the Cardinals have brought in for 2015.
The Cardinals didn't draft an inside linebacker, but coach Bruce Arians said he needed more at the position, and that was reflected in the team's list of undrafted rookies who have agreed to terms.
The group, announced Tuesday, includes BYU's Alani Fua, Bowling Green's Gabe Martin, Georgia Southern's Edwin Jackson and Florida Atlantic's Andrae Kirk, all who figure to be inside linebackers in the Cards' system.
The Cardinals needed to make three roster moves Tuesday to clear space for the rookies. Tight end John Carlson announced his retirement, and the Cards released running back Zach Bauman and cornerback Roc Carmichael.
Rookies arrive Thursday, with rookie minicamp starting Friday. The full undrafted list:
Adams State CB Cariel Brooks
N.C. State T Rob Crisp
