Dolphins up 3-0, Dre Greenlaw questionable with calf injury

The Dolphins have an early lead on the 49ers in Miami.

Jason Sanders hit a 44-yard field goal to end the Dolphins' second possession of the day and they lead the 49ers 3-0 with 3:30 left in the first quarter. It looked like the Dolphins might be able to get six, but a Tua Tagovailoa pass to wide receiver Tyreek Hill in the end zone was altered just enough by Deommodore Lenoir to force an incompletion.

The 49ers defense took a hit before the field goal when linebacker Dre Greenlaw left with a calf injury. Greenlaw, who was questionable with Achilles and knee issues coming into the game, has been called questionable to return.

The 49ers have punted on both of their possessions with a Jordyn Brooks sack helping to spoil their second one.
