Watch: Kaepernick hits wide-open Smith for 1st TD pass of season

Colin Kaepernick is back under center for the San Francisco 49ers, and he wasted little time making an impact.

Early in the second quarter of Sunday's game against the Buffalo Bills, Kaepernick found a wide-open Torrey Smith for a 53-yard catch-and-run touchdown connection.

It's Kaepernick's first TD pass since Oct. 18, 2015.
