2:25pm: Thomas has landed on injured reserve, per a team announcement. That move confirms he will join Murphy-Bunting in missing the entire 2025 campaign. Fellow cornerback Jaden Davis – who inked a futures deal in January – is also on IR.

11:56am: Cardinals cornerback Starling Thomas suffered a torn ACL during Friday’s practice, as ESPN’s Adam Schefter reports. Thomas will likely miss all of 2025 as a result.

Thomas, 25, signed with the Lions as an undrafted free agent in 2023. He impressed in his first training camp with Detroit but was unable to make the club’s 53-man roster at the end of the summer. The Cardinals claimed him off waivers, and by the end of his rookie season, he had become a full-time starter.

He continued to operate in that capacity in 2024, appearing in a full complement of games and starting 15 of them en route to a 75% snap share. While his peformance last season was certainly an improvement on his rookie showing, he has not yet made much of an impression in terms of surface-level stats or advanced metrics.

Pro Football Focus assigned Thomas an uninspiring 60.9 overall grade (with a matching coverage grade) in 2024, which placed him 76th out of 116 qualified corners. The UAB product also surrendered a 100.6 quarterback rating and is still waiting for his first career interception. He tallied just six passes defensed in his 820 defensive snaps last year.

While ESPN’s Josh Weinfuss believes the Cardinals are well-equipped to withstand Thomas’ absence, the team was seemingly counting on him to remain a key contributor in the secondary. As Theo Mackie of the Arizona Republic writes, Thomas and second-round rookie Will Johnson were splitting reps at one outside corner spot, with 2024 second-rounder Max Melton getting the lion’s share of the looks on the opposite side.

With veteran Sean Murphy-Bunting set to miss the entire 2025 campaign as well, the Cardinals could look to the free agent market for reinforcements. The team’s CB room is comprised largely of young talent like Melton, Johnson, 2023 third-rounder Garrett Williams, 2024 third-rounder Elijah Jones, and fifth-round rookie Denzel Burke.

On the other hand, as Weinfuss suggested when Thomas first suffered the injury (video link), Arizona may feel it has enough depth even without Murphy-Bunting and Thomas in the mix.
