Ihenacho started 17 games for Denver last season, including three in the postseason. He recorded 73 tackles, six passes defensed and forced three fumbles. He's considered a strong safety -- a physical player who is better in the box and struggles when having to cover in space. That likely would be the role he plays for Washington, which is seeking a temporary replacement for suspended safety Brandon Meriweather. He'll miss the first two games of the season.
Ihenacho played 17 games in two seasons for Denver, but became expendable when the Broncos signed free agent T.J. Ward. Also, Quinton Carter returned after missing last season with an injury. Ihenacho is considered a strong special-teams player as well.
Davis was part of the Redskins' initial 53-man roster, completing a journey that began as an undrafted free agent in 2013 with Seattle. But he did not play in the NFL last season. He made an impact with his energetic special-teams play this summer, but is still learning from scrimmage.
