The Indianapolis Colts pulled off an emotional 30-27 surprise win over the Green Bay Packers while the Atlanta Falcons moved to 5-0 in the National Football League.
The Baltimore Ravens ground out a 9-6 win over the host Kansas City Chiefs while a late field goal gave the Pittsburgh Steelers a 16-14 win over the visiting Philadelphia Eagles.
It had been a tough week for the Colts, who revealed last week that head coach Chuck Pagano is in hospital after being diagnosed with leukemia, but rookie quarterback Andrew Luck showed his class in rallying his team to an inspiring win.
Luck, the first pick in April's NFL Draft, put his team ahead with 35 seconds remaining after finding Reggie Wayne with a four-yard pass to cap a 13-play, 80-yard drive that brought unavoidable comparisons with his predecessor Peyton Manning.
