In the 49ers/Bengals game from 12/9/1990 (
http://www.pro-football-reference.com/boxscores/199012090cin.htm), the boxscore has the Bengals leading 17-14 after 3 quarters thanks to a TD run by Ickey Woods. Actually that TD run happened in the 4th quarter, with 12:26 left to play, so the scoring summary needs fixed to show the 49ers leading 14-10 after 3 quarters, with that Ickey Woods 1 yd TD run coming in the 4th quarter.
I confirmed the Bengals scoring in the 4th with the official gamebook and this link
