Arizona Cardinals cornerback Starling Thomas V will miss the 2025 NFL season after sustaining a knee injury on Friday at training camp.

“He’s played a lot of good football for us,” Arizona coach Jonathan Gannon said on Sunday. “… It’s probably the worst part of my job, when you talk to him.”

The Cardinals placed the former Ramsay High School and UAB standout on injured reserve on Sunday. Thomas suffered a torn anterior cruciate ligament in his left knee at practice, the team announced.

“God is good,” Thomas posted on social media after the injury. “Will always trust him in the good times and bad times. My faith and trust will not waiver. #ShakeBack.”

Of the undrafted players who entered the NFL in 2023, Thomas started the most games over the past two seasons with 22.

A three-year starter at UAB, Thomas earned first-team All-Conference USA recognition in 2022. But he went undrafted in the 2023 selections.

After starting three preseason games for Detroit in 2023, Starling got cut in the Lions’ roster reduction for the regular season and came to the Cardinals as a waiver claim on Aug. 30, 2023.

Thomas started seven games as a rookie and 15 in 2024.

Arizona cornerback Sean Murphy-Bunting already is out for 2025 because of an offseason injury after starting 15 games in 2024.

To fill Thomas’ spot on the roster, the Cardinals signed cornerback Steven Gilmore Jr., who played for the Birmingham Stallions during the 2025 United Football League season.

Before UAB and the NFL, Thomas played for Ramsay’s AHSAA Class 6A football championship team in 2016.
