On a five-game winning streak with sizable victory margins of late, Kansas City was favored by 3½ points; the Raiders had won their last eight, but had close calls in the last three. The teams had split the season series, each winning at home. Oakland quarterback Daryle Lamonica torched the Chiefs for five touchdown passes, while the Raiders defense intercepted four passes from Chiefs quarterback Len Dawson and held KC to a pair of field goals in the second quarter. In the first half alone, Lamonica had completed nine passes for 220 yards and four touchdowns.
