Baltimore placed Madubuike (neck) on the active/PUP list Saturday, Clifton Brown of the team's official site reports.
Madubuike missed most of last season due to a neck injury, and he ultimately underwent surgery this April. As such, the veteran defensive tackle is not yet ready to practice. There's been optimism that Madubuike will be able to play in 2026, but a timeline for his return is hazy.
