49ers tie Raiders on Brock Purdy TD pass to Brandon Aiyuk

WATCH: Brock Purdy finds wide open Brandon Aiyuk for TD vs. Raiders.

The 49ers didn’t face much resistance on their first offensive series Sunday. Christian McCaffrey did a lion’s share of the work on the eight-play, 67-yard drive. He carried the ball three times for 53 yards, and his 37-yard dash set the 49ers up with a first-and-goal at the 1. Two plays later it was Brock Purdy finding a wide open Brandon Aiyuk for a touchdown to tie the game at 7.
