However, this could change as Fangio and Roman have drawn interest from the Washington Redskins and Minnesota Vikings, respectively, according to Adam Schefter and Albert Breer.
It's unknown whether both coordinators are interested in a head coaching job or not. Roman's name has previously been linked to the college level at Penn State in 2011 and the University of Tennessee in 2012.
Jim Harbaugh said he expects several coaches on his staff to be interviewed in the coming weeks, which he specifically mentioned defensive line coach Jim Tomsula. He had nothing but praise for his staff in what they have done.
"I imagine there will be some interviews taking place in coming weeks," Harbaugh said on Monday. "[It's] smart on their part [and there] is nobody with a better staff than we [have] here. You wonder sometimes why it’s taken this long. People [are] looking for coaches. If you want [the] one-year flash, sometimes people hire that."
Tomsula has previously served as the interim head coach in Week 17 after Mike Singletary was fired in 2010. Both Roman and Fangio have no head coaching experience at the college or NFL level.
Teams can interview assistants this week on playoff teams. Once the divisional games begin, the 49ers assistants cannot be interviewed unless they are eliminated from the postseason, or during the Pro Bowl week.
