Speaking on Monday, coach Jim Harbaugh backed his coach when asked if Roman will remain the play-caller.
"Yes," Harbaugh answered, per the San Jose Mercury News' Tim Kawakami. "(I) have unwavering support for all our coaches and our players."
Harbaugh after the game said he always "evaluates" his offense, but at this point no changes will be made.
The head coach was also asked Monday about his own future, amid persistent reports that he will be gone from San Francisco after the season.
According to reporters, Harbaugh repeatedly said his only plan was to "attack this week" and that he doesn't concern himself with anything down the line.
