Watch: Raiders backups take the ball away from 49ers starters

Early in the second quarter, the 49ers still had their first teamers in the game against the Raiders crew of backups and fringe players. The first couple drives, the 49ers drove for scores. The second drive they marched down and scored the touchdown easily.

Then the Raiders turned the ball over when Dylan Laube fumbled it away. So, it looked like the 49ers might score a third time. Then the Raiders defense stepped up and took it right back.

Janarius Robinson had been terrorizing Brock Purdy all day. This time, he forced Purdy to make a quick throw and Sam Webb was there to defend it. And there was Christopher Smith to pluck it out of the air and pick it off.
