Robinson’s sack was one of three for the Dolphins and the defense did a good job of keeping the 49ers from generating momentum over the course of the afternoon. Purdy finished 26-of-40 for 313 yards and he had two touchdowns to go with the pick while the injury-ravaged running back corps did little to move the ball on the ground.

Tua Tagovailoa threw the 100th passing touchdown of his career, and the Miami Dolphins defeated the San Francisco 49ers on Sunday.
