Flores will be on the opposite sideline as Shanahan when the Falcons and Patriots face each other in Super Bowl LI on Sunday.
Flores has been with New England during his entire NFL coaching career, starting as a scouting assistant in 2004. From 2012 until 2015, he coached the safeties and then worked with the linebackers in 2016.
Ian Rapoport of NFL Network reported that Los Angeles Chargers linebackers coach Robert Saleh could be a candidate as well.
