The Falcons signed Igwebuike to their active roster Saturday ahead of Sunday's Week 1 matchup with the Panthers, Terrin Waack of the team's official site reports.
With Cordarrelle Patterson (thigh) questionable, Igwebuike has been promoted to provide depth behind Bijan Robinson and Tyler Allgeier in the backfield. With the latter two expected to carry most of the offensive workload, Igwebuike's most likely path to contribute will presumably be through special teams.
