Third quarter
The second half was a parade of turnovers, sloppy play, penalties, and missed opportunities.

Colts returner Jim Duncan fumbled the opening kickoff of the second half and Dallas recovered. Then the Cowboys drove to the Colts' 1-yard line, but Mike Curtis punched the ball loose from Cowboys running back Duane Thomas before crossing the end zone, and the Colts took over at the 1 as Duncan… More was credited with the recovery–-a controversial call because when the resulting pile-up was sorted out, Dallas center Dave Manders was holding the ball. The energized Colts then drove to the Cowboys' 44-yard line 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 their own 1-yard line where it was downed by center 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.[11]

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