First quarter

•  Impact player: The Dolphins were looking out for running back Steven Jackson, yet it was Daryl Richardson who did the damage on the ground early. Jackson, third on the Rams’ depth chart, cut the corner and picked up 44 yards on the second play of the game. Richardson’s big run set up a 48-yard field goal by Greg Zuerlein to give the Rams the early lead. Zuerlein scored all six of the Rams’ first quarter points.

•  Highlights: The Miami offense offered up few of these in the opening quarter — save for a couple of nice catches on short slants from Davone Bess. The Dolphins did little on offense as the Rams held Miami to 32 yards off nine plays.

•  Lowlights: The Dolphins secondary got lit up on St. Louis’ second possession as safeties Reshad Jones and Chris Clemons got beat on a 65-yard pass from Sam Bradford to Chris Givens

Second quarter

Impact player: After a slow start, Ryan Tannehill picked things up on Miami’s second possession of the quarter by leading the Dolphins on a six-play drive in which he completed four passes for 60 yards — including a can’t-believe-he’s-that-open pass to Marlon Moore to give Miami its first lead.

•  Highlights: Miami made two consecutive big plays in the quarter that led to 10 points. First, Moore burned a snoozing Janoris Jenkins for an easy 29-yard scoring catch. On the ensuing kickoff, Jimmy Wilson forced Brit Miller to fumble with Marcus Thigpen recovering.

•  Lowlights: The Dolphins offensive line had a series to forget early in the quarter as there were a total of four penalties called deep in Miami territory. On the final play of the first, Richie Incognito was called for holding then was later flagged for a personal foul. Jake Long was called for hands to the face (declined) as well as a holding.

Third quarter

•  Impact player: Tannehill had another strong quarter as he completed eight of 11 passes for 61 yards. Tannehill opened the third by completing seven passes in the opening drive, including a 1-yard scoring pass to Anthony Fasano.

•  Highlights: Tannehill marched the Dolphins downfield in impressive fashion to start the second half. Miami went 62 yards (Thigpen had a 44-yard return on the kick) on 10 plays with Tannehill capping things off with the short scoring pass to Fasano.

•  Lowlights: Not long after Sam Bradford’s apparent fumble (recovered by Jared Odrick) was ruled an incomplete pass, Miami got beat on the review again when Chris Givens’ catch and fumble (recovered by linebacker Jason Trusnik) was ruled an incomplete pass. Both times, Miami didn’t lose much (save for some good field position) on the rulings as the Rams were forced to punt.

Fourth quarter

•  Impact player: Bradford led the Rams on their scoring drive in the fourth by going 6-for-7 for 32 yards before leaping across the goal line on fourth-and-1 with 8:30 left. The rams also made the two-point conversion.

•  Highlights: Reggie Bush gave an extreme effort when he took the corner on a third-and-1 and leapt over Cortland Finnegan. Only Bush was hit in air by Jo-Lonn Dunbar and stopped inches short of the first down. Miami then faked the punt with Clemons taking the snap and going 3 yards with 4:15 left. Miami ended up punting anyway to give the Rams life after the two-minute warning.

•  Lowlights: The Rams were able to convert a pair of fourth downs during a touchdown drive that lasted 11 plays and 62 yards. Bradford and Brandon Gibson hooked for an eight-yard gain on fourth-and-2 from the Miami 41. On the second, Bradford scored from the 1.
