The Cardinals waived Keke on Sunday, Darren Urban of the Cardinals' official site reports.
Keke had missed more than a week of camp after landing on the COVID-19 list and was part of the first wave of roster cuts the Cardinals made before Tuesday's 85-man deadline. The 2019 fifth-round pick has 6.5 sacks across 27 appearances the last two seasons, but he's struggled to consistently make an impact. Once he clears COVID, he'll look to land on another roster before the start of the regular season.
