first play of the ensuing drive as Mark Bavaro caught a pass from Simms for twelve yards on the first play from scrimmage. Simms followed that up with an eight-yard completion to Stacy Robinson, and two plays later Morris picked up a first down with a short run. The drive stalled there, and the Broncos got the ball back on their 15. Elway was sacked on the first play of the ensuing drive, setting up a second down. What followed was one of the more crucial calls of the game. With the ball on the Denver 13, Elway found Clarence Kay for a gain of 25 yards and an apparent first down. However, referee Jerry Markbreit conferred with his crew and reversed the call, determining that Kay had not controlled the football before being tackled. However, the discussion among the crew continued for some time before NFL Director of Officiating Art McNally paged umpire Bob Boylston; this meant that, for the first time, the newly introduced instant replay system would be used in a Super Bowl. The crew then waited while McNally and the officials in the replay booth took a second look at the play. They ruled that the play would stand as called, as an incomplete pass. Indeed, there were no conclusive replays that the officials could find that indicated Kay caught the pass. CBS, however, was able to find one that the officials had not seen; the production crew found a reverse angle shot of the play that proved conclusively that Kay caught the pass cleanly. The network broadcast this replay toward the end of the first half. The Giants managed to capitalize on the next play as Elway, under pressure, retreated into the end zone and was tackled there by veteran defensive lineman George Martin, giving up a safety and cutting the Broncos’ lead to 10–9. The defense, however, was able to hold the Giants to a three-and-out on the drive following the ensuing free kick. With 1:09 left in the half, Elway started from his own 37-yard line. On second down, he completed a 31-yard pass to receiver Steve Watson and then an 11-yard pass to Willhite, giving the Broncos a first down at the Giants 21. They moved the ball to the New York 16-yard line, which resulted from a penalty on Jim Burt for jumping offsides, but the Giants forced two incompletions. The
