The San Francisco 49ers’ quarterback situation is uncertain, leading to the Week 5 matchup against the Miami Dolphins. Starter Jimmy Garoppolo is nursing a high ankle sprain that caused him to miss the last two games. Nick Mullens played well in place of Jimmy G against the New York Giants, but performer horribly in the Week 4 loss to the Philadelphia Eagles.
Niners head coach Kyle Shanahan yanked Mullens after a pick-six against the Eagles and went with C.J. Beathard the rest of the way.
