HOUSTON (AP) — Andrew Luck threw for 222 yards and two touchdowns and Indianapolis raced out to a big lead and cruised over Houston in the wild-card game.
Luck put on a show in his hometown, throwing for 191 yards and two touchdowns before halftime to help the Colts (11-6) build a 21-0 lead.
Running back Marlon Mack had 148 yards and a touchdown for Indianapolis, which advances to face the top-seeded Kansas City Chiefs in the divisional round next weekend.
Houston (11-6), which overcame a 0-3 start to win the AFC South, gave up too many big plays and couldn't get anything going on offense in the first half to fall into the huge hole.
Deshaun Watson, who was sacked an NFL-leading 62 times in the regular season, was sacked three times and hit eight more times in a disappointing playoff debut. He finished with 235 yards passing with a touchdown and an interception.
The Colts, who opened the season 1-5, continued an impressive run by winning their fifth straight and for the 10th time in 11 games. Saturday was their first playoff appearance since the AFC championship game loss at New England in the "Deflategate" game in the 2014 season.
