Those three points give Baltimore its first points in the first quarter since the season opener at Denver.
The Ravens made it happen by stalling the Dolphins on the game's first drive, using an impressive stand following a 9-yard pass on first down. Baltimore kept Miami from converting a first down by stopping the rush on second-and-1 and third-and-1.
On third down of the Ravens' first offensive drive, Joe Flacco connected with Smith for a short pass that the No. 1 wideout turned into a 41-yard gain. Flacco will need some more of that from Smith this afternoon with just three wideouts dressed since Jacoby Jones and Marlon Brown are out.
Update: The Dolphins capitalized on a Ravens miscue to draw even with the Ravens at 3-3 with 2:16 to go in the first quarter.
Ray Rice fumbled and former Ravens linebacker Dannell Ellerbe recovered it at the Baltimore 29, setting up Caleb Sturgis for a 37-yard field goal.
It was a disappointing moment for Rice, who was making his sixth carry of the game one week after Baltimore called a franchise record-low nine running plays. If Rice wants the Ravens to stick with the running game, he can't be making mistakes like that.
Update II: Another big play in the passing game set up Tucker's second field goal of the game, a 50-yarder that gave the Ravens a 6-3 lead with 11:52 to go in the first half.
Struggling tight end Ed Dickson made a tough catch with space in front of him for a 43-yard gain to put Baltimore on the Miami 29. It was Dickson's longest reception of the year by 30 yards. He entered the day with just three catches for 25 yards in four games.
Tucker's field goal makes him 7-for-7 since going 0-for-2 in the win over Cleveland. It was his first conversion from at least 50 yards out this season.
Flacco continues to have an up-and-down day. He has two passes of at least 40 yards, for a combined 84 yards to be exact. But outside of that, he's 3-for-8 for 22 yards.
Update III: Miami answered again, tying it at 6-6 on Sturgis' 25-yard field goal with 8:07 remaining in the second quarter.
On the drive, Ryan Tannehill hooked up with wideout Mike Wallace three times for 69 yards, including a 49-yarder.
Update IV: Compounding the continued offensive line and running game struggles are the sudden problems of punter Sam Koch, who has two boots of just 26 yards.
Koch's latest 26-yard punt started Miami at its own 40, and the Dolphins were able to take advantage for the game's first touchdown.
The Dolphins drove 60 yards in seven plays and 1:09 to take a 13-6 lead on Tannehill's 9-yard touchdown pass to Charles Clay with 46 seconds to go in the first half.
Tannehill completed back-to-back passes to Brian Hartline for a combined 51 yards to set up first-and-goal. Three plays later, Tannehill found Clay.
