According to CBS Sports Matt Zenitz, Indianapolis Colts defensive quality control coach Brent Jackson is set to join the Arizona Cardinals coaching staff under their new head coach Mike LaFleur:

Having joined the Colts in May of 2022, Jackson just finished his 4th season as Indianapolis' defensive quality control-after previously working as a graduate assistant with defensive backs on the University of Oregon's coaching staff.

He earned the Tony Dungy Diversity Coaching Fellowship thereafter and got his initial start in Indy.

Jackson was retained following the transition from former defensive coordinator Gus Bradley to veteran defensive coordinator Lou Anarumo ahead of last offseason.

There's been largely minor coaching turnover in Indianapolis, as the biggest change has been made at defensive line coach, where Charlie Partridge returned to the college ranks, and Marion Hobby was recently named his replacement. However, there have been a few other tweaks here and there.

As for Jackson, he'll be joining returning Cardinals defensive coordinator Nick Rallis back in his familiar footing as an assistant defensive backs coach.

It'll be interesting to see who replaces Jackson at his vacant Colts defensive coaching position. The Colts defense faces some lingering question marks regarding the health of veterans DeForest Buckner and Charvarius Ward, as well has a greater need to get faster and younger collectively as longtime general manager Chris Ballard noted in his end-of-season press conference.
