The Colts defensive end doesn't seem to be having any problems with his injured right ankle.
Freeney's sack forced the Saints into kicking a 46-yard field goal.
The All-Pro defensive end played almost every play in the first quarter, and twice got close to Brees before finally getting to him.
Freeney had been listed as questionable after tearing a ligament in his right ankle late in the AFC championship game.
But the injury didn't keep him out of the game — or out of the Saints backfield.
He worked out on the field less than two hours before kickoff at Sun Life Stadium and repeatedly overpowered the Saints offensive linemen.
