Baltimore dominated the first quarter, holding the Raiders to six plays and one completion, while Unitas led them to the 4-yard line where Jim O'Brien's 16-yard field goal gave them a 3–0 lead.
In the second quarter, a massive hit by Colts lineman Bubba Smith knocked Oakland QB Daryle Lamonica out of the game, and he was replaced by George Blanda.
Later on, Raiders defensive back Willie Brown narrowly dropped an interception on a deep pass from Unitas.
But returner George Atkinson fumbled David Lee's kick and the Colts running back Sam Havrilak recovered with excellent field position.
Unitas then completed a 43-yard pass to Eddie Hinton at the 2-yard line, and Norm Bulaich scored a touchdown run on the next play, increasing the lead to 10–0.
Blanda then led the Raiders back, and with the aid of a roughing the punter penalty, he got them close enough for a 48-yard field goal, which he kicked himself to cut the score 10–3 at the end of the half.
Unitas responded with two key long completions to Hinton that set up O'Brien's 23-yard field goal to retake the lead at 13–10.
On the next play, Unitas threw a deep pass to a wide open Ray Perkins, who raced down the left sideline for a 68-yard touchdown completion that gave the Colts a 27–17 lead.
[1] This would prove to be the last score of the game as the Raiders were shut out in the final 12 minutes, with Blanda throwing two interceptions deep in Baltimore territory.
Colts linemen Bubba Smith and Ray Hilton each had two sacks, along with Raiders lineman Ben Davidson.
