This move reunites Bradley with new 49ers defensive coordinator Robert Saleh, with whom he previously worked at both the Seattle Seahawks (2011-12) and Jacksonville Jaguars (2014-16).
Bradley most recently served as the Indianapolis Colts' defensive coordinator for the past three seasons. Prior to that, he held similar roles with the Las Vegas Raiders (2021) and Los Angeles Chargers (2017-20). Bradley was the Jaguars' head coach from 2013 to 2016.
Shanahan initially tried to hire Bradley as his defensive coordinator in 2017 before ultimately landing on Saleh. Bradley joined the Chargers that offseason.
Bradley's NFL coaching career began in 2006 as the linebackers coach for the Tampa Bay Buccaneers. He then moved on to serve as the Seahawks' defensive coordinator from 2009 to 2012.
His official role with the 49ers has yet to be confirmed.
