The Broncos placed Ojemudia (elbow) on injured reserve Wednesday, Aric DiLalla of the team's official site reports.
Ojemudia made the initial 53-man roster, but he'll land on IR and miss at least the first four games of the regular season. The 2020 third-round pick was jockeying for a depth role in Denver's competitive secondary before he dislocated his elbow in mid-August.
