Here's what the wiki has on Nnamdi Madubuike's situation (from the Nnamdi Madubuike page):
Yes, he's expected to return to the Ravens in 2026 — assuming he gets medical clearance. Madubuike is still under contract (four-year, $98M extension signed before 2024) and has never been a free agency or trade candidate.
The key variable is his health. He underwent neck surgery in April 2026 after a Week 1 injury in 2025 sidelined him for the rest of that season. On July 16, Ravens GM Eric DeCosta said Madubuike is "trending in the right direction" and that the team expects clarity on his playing status within weeks.
Before the injury, he'd played 55 consecutive games and had 2 sacks in just two games to start 2025, so the team clearly sees him as a core piece when healthy.
