The Arizona Cardinals strengthened their defensive lineup on Thursday, signing linebacker Stephen Dix to their 90-man roster. This move marks the eighth undrafted rookie the Cardinals have brought on board since last month's draft concluded, signaling a focus on building depth through young talent.

Dix brings a diverse collegiate background to the desert. After starting his career at Florida State, he spent time at Marshall before landing at Arkansas for the past two seasons. With the Razorbacks in 2025, he posted solid numbers: 79 tackles, four tackles for loss, and a sack. His experience across multiple programs suggests a player who can adapt quickly—a valuable trait as he fights for a roster spot in training camp.

The Cardinals' linebacker room is shaping up with a mix of draft picks and free agents. They selected Karson Sharar in the sixth round of the NFL Draft and added Jack Gibbens via free agency. Returning veterans like Mack Wilson, Cody Simon, Owen Pappoe, and Austin Keys round out the unit. For fans watching the depth chart, Dix's path to making the final roster will hinge on his performance in preseason battles—and whether he can stand out in a competitive group.
