The second quarter of the Kansas City Chiefs at Miami Dolphins game started with the Chiefs facing a 4th-and-1 play, one they easily converted. The play kept a drive alive that started with a 33-yard punt return, but was not able to to keep it going as they would lose three yards on a Knile Davis run, followed by a four-yard gain from Davis, and, finally, Miami's third sack of the game, this one credited to Jason Trusnik. The Chiefs would punt, with the ball downs at the Miami 17-yard line.
The Dolphins came out on the next drive and moved the ball through the air, with Mike Wallace beginning to have an impact. On first down, Ryan Tannehill connected with him for a 30-yard gain on the catch and run, then Tannehill came right back to Wallace on the next play, connecting for another 15 yards. Lamar Miller added five yards on the ground, followed by another dropped pass, the third on the day for Miami receivers, this time from Brandon Gibson. Gibson would catch the next pass for three yards, but Caleb Sturgis would miss a 48-yard field goal.
The Chiefs would not miss on their first real scoring opportunity, taking the ball straight down the field on Miami. After a run for no gain from Davis, Alex Smith connected with Dwayne Bowe for a 16-yard completion down to the Miami 46-yard line. A couple of plays later, Davis made up for his no-gain play with a 21-yard touchdown run, giving Kansas City the 7-0 lead.
Miami's offense again came out and did nothing on their next possession, with one good run from Miller who picked up 20 yards on a 2nd-and-10 run. Tannehill was sacked on the drive, fumbling the ball, but luckily having it bounce back to him. One incomplete pass later, and the Dolphins were punting for their fourth time on the day.
Kansas City resumed their march against the Miami defense on the next drive, going 76-yards in eight plays. They scored on a 20-yard pass from Smith to Travis Kelce, who dove for the pylon after a weak tackle attempt from Miami cornerback Cortland Finnegan. The score extended the lead to 14-0.
The Dolphins offense came out in the two-minute offense and actually found some rhythm. Tannehill connected with Miller, Wallace, Landry, and Thomas on the drive, as well as running for nine yards, on a drive that moved 74 yards in eight plays in a little over a minute-and-a-half. Sturgis connected on the 22-yard field goal as time expired to make the halftime score 14-3.
