The Raiders elevated Okwuegbunam from their practice squad Saturday ahead of Sunday's matchup versus the Bears.
Okwuegbunam will likely serve as the team's No. 3 tight end Sunday behind Brock Bowers and Ian Thomas, as Michael Mayer has been ruled out with a concussion. Okwuegbunam can contribute on both offense and special teams. He will be eligible to be elevated two more times this season.
