The first half went scoreless, as both teams struggled to move the ball with a light snow and driving wind hampering their efforts. Baltimore drove to midfield but lost the ball on a fumble by fullback Jerry Hill. The Browns then moved to the Colt 35 but Paul Warfield slipped going for a Ryan pass and the ball was intercepted by Colt linebacker Don Shinnick. As the second quarter began, Baltimore had moved deep into Browns territory. The Colts attempted a 27-yard field goal by Lou Michaels, but holder Bobby Boyd had to reach for the snap from center and was hauled down behind the line of scrimmage. Near the end of the first half, Unitas got another drive going into Cleveland territory. However, from the Brown 46 he threw slightly behind tight end John Mackey, who could only deflect the pass; it was intercepted by Vince Costello. The scoreless first half ended after Ryan missed on a long pass to Warfield.
