One pass, one touchdown. 

Trey Lance's start to his NFL career couldn't have gone much better. Kyle Shanahan unveiled the 49ers' two-QB system Sunday in Detroit and it was executed to perfection against the Lions. 

Lance entered the game for Jimmy Garoppolo on second-and-9 from the 16-yard line and rushed up the middle for 1 yard. He then entered again three plays later and perfectly hit receiver Trent Sherfield for a 5-yard pass touchdown, giving the 49ers an early 6-0 lead. 

Robbie Gould's extra-point made it 7-0 in San Francisco's favor.

Garoppolo started at quarterback for the 49ers and fumbled the snap on their first play.
