SAN FRANCISCO – Andrew Luck threw for 164 yards and ran for a 6-yard touchdown while facing college coach Jim Harbaugh for the first time, and the Indianapolis Colts defeated the San Francisco 49ers 27-7 win Sunday.
Trent Richardson scored a 1-yard touchdown on his first carry in his Colts debut after being acquired on Wednesday from the Browns. He was drafted two spots behind top pick Luck at No. 3 last year.
Ahmad Bradshaw added a 1-yard TD run in the final minutes, and Adam Vinatieri kicked a pair of field goals before missing a 51-yarder early in the fourth.
It was Colin Kaepernick's first home loss at Candlestick Park as a starter.
There were few bright spots for Kaepernick as San Francisco struggled to establish a passing game with tight end Vernon Davis sidelined by a hamstring injury.
