On the Colts’ first drive at San Francisco, Andrew Luck’s fine passing got the Colts deep into 49ers’ territory.
Then, new tailback Trent Richardson punctuated the possession in style, rushing for a one-yard touchdown to give the Colts a 7-0 lead.
The touchdown came on Richardson’s first carry for the Colts, who acquired him from Cleveland on Wednesday.
On the touchdown, the Colts’ offensive line opened a crease for Richardson, and he sprinted into the endzone.
Luck completed all five of his passes on the Colts’ first possession.
The Colts and 49ers are tied at seven in the latter stages of the first quarter.
