Editing Super Bowl V (section)

===Fourth quarter===
However, three plays later, on the first play of the fourth quarter, Morrall threw an interception to Howley in the end zone to preserve the Cowboys' 13–6 lead.<ref name="USA Today Super Bowl V Play by Play">{{cite news|title=Super Bowl V play-by-play|url=https://www.usatoday.com/sports/nfl/super/superbowl-v-plays.htm|work=USA Today|date=January 11, 2002}}</ref>

After forcing the Cowboys to punt, the Colts regained the ball on their own 18-yard line, still trailing 13–6. Aided by a pass interference penalty on Dallas safety [[Charlie Waters]] and a 23-yard pass from Morrall to Jefferson, the Colts advanced into Dallas territory. A second pass interference penalty, which was called on defensive back [[Cornell Green (defensive back)|Cornell Green]], gave the Colts a first down at the Dallas 39-yard-line. An 8-yard run by Nowatzke moved the ball to the 31-yard line. The Colts then attempted to fool the Cowboys with a [[Flea flicker (American football)|flea-flicker]],<ref name=OBrien/><ref name=McGrane/><ref>"Super Bowl V," ''Super Bowl I-X Collector's Set.'' NFL Productions, LLC, 2003</ref> resulting in one of the oddest plays in Super Bowl history. Havrilak took a handoff and ran right, intending to lateral the ball back to Morrall, but Pugh stormed into the backfield and prevented him from doing so. Havrilak (who played quarterback at [[Bucknell University]]) then threw a pass intended for Mackey, but it was caught instead by Hinton, who promptly took off for the end zone. However, Green stripped Hinton from behind at the 11, and the loose ball bounced wildly into the end zone, evading recovery attempts by six different players until it was eventually pushed through the back of the end zone for a touchback, thus returning the ball to the Cowboys at their 20.

Three plays after the turnover, Morton threw a pass that was deflected by Garrison and intercepted by Colts safety [[Rick Volk]], who returned the ball 30 yards to the Cowboys' 3-yard line before being tackled by wide receiver [[Reggie Rucker]] (Morrall later referred to that play as the play of the game).<ref name=McGrane/> Two plays later, Nowatzke scored on a 2-yard touchdown run, tying the game at 13–13. (O'Brien says he was much calmer and more confident on this extra point than on the first one, which was blocked.)

The next two possessions ended in traded punts, with the Cowboys eventually taking over in excellent field position at the Colts 48-yard line with less than two minutes left in the game.

On the second play of this potential game-winning drive, a 15-yard holding penalty on Cowboys offensive tackle [[Ralph Neely]] on the Dallas 42-yard line, which was a spot foul, pushed the Cowboys all the way back to their own 27-yard line (the NFL did not reduce the penalty for offensive holding to 10 yards until 1974).<ref>{{cite web |url=http://static.nfl.com/static/content/public/image/history/pdfs/History/Chronology.pdf |title=Chronology of Professional Football |archive-url=https://web.archive.org/web/20120309110019/http://static.nfl.com/static/content/public/image/history/pdfs/History/Chronology.pdf |archive-date=March 9, 2012}}</ref> Then, on 2nd-and-35, Morton threw a pass that slipped through the hands of Reeves and bounced for an interception into the arms of Mike Curtis, who then returned the ball 13 yards to the Cowboys' 28-yard line.

Two plays later, with nine seconds left in the game, O'Brien kicked the go ahead 32-yard field goal, giving Baltimore their first lead of the game, 16–13.<ref>Jim O'Brien says there is a widespread notion that he was so nervous before his game-winning field goal, he forgot he was on artificial turf and attempted to pick up grass to test for wind. He says he was actually picking up lint from the players' jerseys.</ref> O'Brien says he was "on automatic" and was so calm and concentrating so hard that he didn't hear anything and saw only the ball.<ref name=OBrien/> After the field goal, in an enduring image, Cowboys defensive tackle [[Bob Lilly]] took off his helmet and hurled it through the air in disgust.

The Cowboys received the ball again on their own 40 with one second remaining after O'Brien's ensuing squib kick, but Morton's pass to Hayes was intercepted by safety [[Jerry Logan]] at the Baltimore 29, and the Colts were victorious.
