Rapp agreed Monday with Buffalo on a one-year contract, Adam Schefter of ESPN reports.
Rapp is now in line to suit up for the Bills in 2023 following Monday's agreement. The 25-year-old has served as the Rams' starting strong safety since he was drafted as a second-round selection by Los Angeles in 2019, and he registered 92 tackles, six passes defensed and two interceptions across 16 contests last season. Although the Bills already have two prominent safety options in Jordan Poyer and Micah Hyde (neck), Rapp is still more than likely to command a rotational role within the team's secondary.
