a combination of AFL and NFL referees, with the NFL's Norm Schachter as the head referee. First quarter The teams traded punts on their first possessions, then the Packers jumped to an early 7–0 lead, driving 80 yards in six plays. The drive was highlighted by Starr's passes, to Marv Fleming for 11, to Elijah Pitts for 22 yards on a scramble, and to Carroll Dale for 12 yards. On the last play, Bart Starr threw a pass to reserve receiver Max McGee, who had replaced re-injured starter Boyd Dowler earlier in the drive. (Dowler had injured his shoulder two weeks prior after scoring a third-quarter touchdown; Cowboy safety Mike Gaechter had upended him several steps after scoring and he landed awkwardly.) McGee slipped past Chiefs cornerback Willie Mitchell, made a one-handed catch at the 23-yard line, and then took off for a 37-yard touchdown reception (McGee had also caught a touchdown pass after replacing an injured Dowler in the NFL championship game). On their ensuing drive, the Chiefs moved the ball to Green Bay's 33-yard line, but kicker Mike Mercer missed a 40-yard field goal. Second quarter Early in the second quarter, Kansas City drove 66 yards in six plays, featuring a 31-yard reception by the receiver Otis Taylor, to tie the game on a seven-yard pass to Curtis McClinton from quarterback Len Dawson. But the Packers responded on their next drive, advancing 73 yards down the field and scoring on fullback Jim Taylor's 14-yard touchdown run with the team's famed Packers sweep play. Taylor's touchdown run was the first in Super Bowl history. This drive was again highlighted by Starr's key passes. He hit McGee for 10 yards on third and five; Dale for 15 on third and ten; Fleming for 11 on third and five; and Pitts for 10 yards on third and seven to set up Taylor's TD run on the next play. Dawson was sacked for an eight-yard loss on the first play of the Chiefs' next drive, but he followed it up with four consecutive completions for 58 yards, including a 27-yarder to Chris Burford. This set up Mercer's 31-yard field goal to make the score 14–10 at the end of the half. At halftime, the Chiefs appeared to have a chance to win. Many people watching the game were surprised how close the score was and how well the AFL's champions were playing.
