Jacksonville waived Kiser (knee) on Sunday, John Oehser of the team's official site reports.
Kiser was selected by the Jaguars in the fourth round of the 2025 NFL Draft and played in 14 regular-season games as a rookie, working primarily on special teams. He wasn't able to make Jacksonville's 53-man roster but cleared waivers and subsequently signed to the Jags' practice squad.
