According to Damon Bruce, a sports personality on KNBR, Billy Davis will be relieved of his duties tomorrow. This is based on a "reliable source" inside the 49ers organization. There is no word as to his replacement.

Billy Davis is in his second year as 49ers defensive coordinator. Many called for his release earlier this year but Nolan supported his defensive coordinator despite many blowout losses to opponents such as San Diego, Chicago, and Kansas City.

Nolan, a defensive minded coach, pretty much co-coordinated the defense this season, yet there is no indication as to his duties if a new coordinator is hired.

It is unknown how reliable Damon Bruce has been in the past with his information.
