INDIANAPOLIS - It looks like Andrew Luck needed only half a season to establish himself as a worthy successor to Peyton Manning.
Luck completed 30 of 48 passes for 433 yards and two touchdowns in the Colts' 23-20 win over the Miami Dolphins on Sunday at Lucas Oil Stadium. The 433 yards set an NFL rookie record. Cam Newton had set the record with 432 yards last season.
Luck also tied Manning's rookie record with his fourth game of 300 or more yards passing. And he still has eight games to break the mark. Luck broke his own Colts rookie record for yardage, surpassing the 362 he threw against the Green Bay Packers.
The win came on the first day ailing Colts coach Chuck Pagano attended a game since being diagnosed with leukemia. Pagano watched the game from Colts owner Jim Irsay's suite.
The Colts improved to 5-3 heading into a Thursday night game at Jacksonville. The Dolphins fell to 4-4.
The Dolphins took over on their own 17 with 2:39 left, trailing 23-20, but the Colts stopped the Dolphins on 4th-and-15, then ran out the clock on offense.
Luck drove the Colts from their own 6-yard line to the Miami 25 to set up the go-ahead 43-yard field goal by Adam Vinatieri with 5:58 left.
The Colts took a 20-17 lead with an 80-yard third-quarter drive as Luck hit rookie receiver T.Y. Hilton on a 36-yard pass. Hilton leaped up in double coverage to haul in the scoring pass with 1:49 left in the third.
Miami answered with a Dan Carpenter 31-yard field goal to tie the game 20-20 with 13:12 left in the fourth.
Quaterback Ryan Tannehill and the Dolphins led 17-13 at halftime. Tannehill had completed 10 of 14 passes for 158 yards and a score, which paled only in comparison to Luck. Luck was 19 of 28 for 273 yards and a score. Only New Orleans' Drew Brees had thrown for at least 270 yards in a first half this season.
Tannehill finished 22 of 38 for 290 yards.
Luck set the tone for the first half with three terrific passes on the Colts? first touchdown drive, escaping potential sacks on two of them. The first was a pass to Reggie Wayne just over the fingertips of Dolphins defensive safety Jimmy Wilson. The second was a 25-yard pass on the run to Hilton. Luck then hit Wayne for a nine-yard score over the middle and a 7-3 lead with 47 seconds left in the first.
Tannehill put the Dolphins back on top with a five-play, 80-yard drive, hitting tight end Charles Clay on a 31-yard touchdown pass to make it 10-7 early in the second quarter. Tannehill was 6-of-8 passing for 112 yards in his first two series.
The Colts tied it 10-10 on their next possession, with Luck driving the team 75 yards and Vinatieri hitting a 23-yard field goal with 9:37 left in the half. At that point of the game, Luck was 12-for-16 for 181 yards and a score.
Reggie Bush delivered the kind of run only Bush can deliver, making two would-be Colts tacklers grasp air as he scored on an 18-yard run to put Miami up 17-10 with 5:07 left in the half. Tannehill hit Bush earlier on 3rd-and-8 to keep the drive alive.
But Luck drove the Colts 58 yards in 74 seconds to set up a 47-yard Adam Vinatieri field goal to close the margin.
Notes: Colts receiver Wayne passed Edgerrin James for third on the team touchdowns list. . . .Colts outside linebacker Robert Mathis recorded a sack in his eighth consecutive game played before leaving the game with a back injury.
