===Third quarter===
The second half was a parade of turnovers, sloppy plays, penalties, and missed opportunities. Baltimore's defense also held Dallas' offense scoreless for the rest of the game.

Duncan fumbled the opening kickoff while running into Cowboys running back [[Claxton Welch]], and Dallas recovered the ball at Baltimore's 31. Then the Cowboys drove to the Colts' 2-yard line with the chance to take a two-score lead, but linebacker [[Mike Curtis (American football)|Mike Curtis]] punched the ball loose from Thomas before he could cross the goal line, and the Colts took over at their own 1 as Duncan was credited with the recovery–-a controversial call because when the resulting pile-up was sorted out, Dallas center [[Dave Manders]] was seen holding the ball. The energized Colts then drove to the Cowboys' 44-yard line, with Morrall completing a 26-yard pass to wide receiver [[Sam Havrilak]], but came up empty when O'Brien's 52-yard field goal attempt fell short of the goal posts. However, instead of attempting to return the missed field goal, Renfro allowed it to bounce inside the Cowboys' own 1-yard line where it was downed by Colts center [[Tom Goode (footballer)|Tom Goode]] (NFL rules prior to 1974 allowed a field goal that fell short of the goal posts to be downed just like a punt; that rule is still in effect in high school football). "I thought it would carry into the end zone", Renfro explained after the game.<ref>{{cite web |url=http://ag.nfl.com/?team=1966 |title= America's Game|website=ag.nfl.com |archive-url=https://web.archive.org/web/20090207192904/http://ag.nfl.com/?team=1966 |archive-date=February 7, 2009}}</ref>

Dallas, backed up to their own end zone, punted after a three-and-out. The Colts would have received the ball inside Dallas territory following the punt, but a clipping penalty on Baltimore running back [[Jack Maitland]] pushed the Colts back to their own 39 to begin the drive. Two plays later, however, Morrall completed a 45-yard pass to running back [[Tom Nowatzke]] to reach the Cowboys' 15-yard line.
