The Broncos signed Rapp off the practice squad to the active roster Saturday, Parker Gabriel of The Denver Post reports.
The addition of Rapp gives the Broncos more depth in the secondary, and he could see some work on defense against the Chiefs on Sunday due to the absence of Talanoa Hufanga (ankle). Rapp played in both Weeks 6 and 7 and logged eight tackles (two solo) over those two appearances.
