The NFL's television ratings for the divisional round playoff games were down 16 percent compared to last season.
The weekend's four games averaged 30.43 million viewers, off from 36.22 million the year before, the Nielsen company said.
Last year's games featured the Green Bay Packers and Dallas Cowboys, which reached more than 48 million viewers.
While ratings were down, Saturday's game between the Patriots and Titans was only one million viewers behind the College Football Championship for the most watched program of the week.
