This is the live blog for the San Francisco 49ers (7-4) week 13 matchup against the Miami Dolphins (8-3) from Levi’s Stadium. I will provide updates and analysis from the press box throughout the game.
11:50 49ers inactives: Curtis Robinson, Ross Dwelley, Spencer Burford, T.Y. McGill
Daniel Brunskill will make his first start of the season in place of Spencer Burford.
Dolphins Inactives: Terron Armstead, Austin Jackson, Erik Ezukanma, Hunter Long, Noah Iginohene, Teddy Bridgewater, Myles Gaskins
Miami will be without both starting tackles, Terron Armstead and Austin Jackson.
1:03 49ers have won the toss and deferred to the second half.
1:06 One play, 75-yard touchdown for Miami.
Tua Tagovailoa hits Trent Sherfield with a quick slant and the receiver splits the defense.
Tagovailoa has been terrific this year working the intermediate middle of the field. The 49ers had to be ready for that.
1:17 Jimmy Garoppolo with a pair of big completions, one to Brandon Aiyuk for 20 yards and one to Christian McCaffrey for 23, but it’s the one he missed that stopped the 49ers drive.
On second and six at the Dolphins 19, Garoppolo had Brandon Aiyuk uncovered on an out route, never saw him and threw instead to George Kittle over the middle. The tight end was well covered and the pass fell incomplete.
Robbie Gould connects from 47 yards out to make it 7-3 Dolphins.
1:20 The 49ers defense forces a three and out.
On third and six, Fred Warner got enough depth to get a hand on a Tagovailoa pass to Trent Sherfield who was open.
Jimmy Garoppolo has an ankle injury, and his return is questionable.
Brock Purdy time.
1:30 Purdy has been a little all over the place on this first drive, but that’s to be expected. The 49ers have used a good mix of runs and play action passes to get into the deep redzone.
1:32 First and goal from the three, Purdy to Juszczyk off play action for the touchdown.
49ers 10 Dolphins 7
San Francisco ran the ball five times for 30 yards on the touchdown drive.
1:37 The 49ers defense gave up a touchdown on the first play of the game but turned it around with back-to-back three and outs.
Strong first down run defense on Jeff Wilson Jr. followed by a pair of incompletions from Tagovailoa to Jaylen Waddle. Good coverage and pressure on both plays from the 49ers defense.
On the third down play, Nick Bosa lined up inside and was in Tagovailoa’s face as he threw.
1:45 Kyle Shanahan tries to go quick on third and two, Miami sniffs out the play and drops Christian McCaffrey for a loss of a couple.
Kyle Shanahan is going to be very conservative with the lead and Brock Purdy in the game.
1:51 There is no way Jimmie Ward is going to keep up with Tyreek Hill.
1:58 Nick Bosa gets through two Dolphins to end the Miami drive with a sack.
Jason Sanders hits the field goal to tie the game at 10.
Mike McDaniel did a good job of giving Tua Tagovailoa several quick throws to get the quarterback into a rhythm on that possession.
2:05 Kyle Shanahan is going into a shell. Can’t blame him, the game is tied, and he has to work with Brock Purdy.
2:09 Three plays, three incompletions by Tua Tagovailoa. The Dolphins had receivers open on first and second down, but the quarterback was inaccurate on both.
2:17 Jordan Mason with a couple of big runs before the 49ers find themselves with fourth and four at the 39. They go for it and Brock Purdy is intercepted on a deep throw down the right sideline to Brandon Aiyuk.
Left guard Aaron Banks gave up a big sack. The second-year guard has struggled with picking up twists the last two weeks.
2:22 This 49ers defense isn’t playing great, but Tua Tagovailoa has played poorly and the pass rush for San Francisco has been able to get home on third and long.
Nick Bosa ends the Dolphins possession with his second sack of the game.
2:36 Brock Purdy has been all over the place with some of his throws but drives the 49ers 76 yards for a touchdown to end the first half.
On third and goal from the three, with no timeouts, Purdy connects with Christian McCaffrey for the score.
WOW. What a performance by San Francisco.
49ers 17 Dolphins 10
2:57 San Francisco opens the second half with a six-play possession. Brock Purdy hit Jauan Jennings over the middle for 15 yards, but then ran into trouble instead of stepping up into the pocket.
3:04 Huge play by Jimmie Ward. Following two personnel foul penalties on the 49ers, the safety steps over River Cracraft for an interception.
Jordan Mason has 37 yards on three carries today. Kyle Shanahan should give him a few here with the ball out at the 35.
3:17 Brock Purdy with a few big throws to open the Niners second possession of the second half.
Kyle Shanahan was aggressive, going for it on fourth and one. However, his aggressiveness got the better of him on the next play when Deebo Samuel was dropped for a loss of four on a reverse.
San Francisco chewed up 7:09 off the clock and Robbie Gould hit from 43-yards out to make it 20-10 49ers.
3:21 Another 49ers takeaway. Tagovailoa’s pass in the right flat goes off the hands of Tyreek Hill and 49ers cornerback Deommodore Lenoir picks it off.
San Francisco has taken away the middle of the field and Tagovailoa has struggled to adjust.
3:25 Taking over at the Dolphins 25, the 49ers offense can only muster seven yards. Robbie Gould connects for his third field goal to give San Francisco a 13 point lead.
3:30 The third quarter comes to a close with the 49ers leading 23-10.
They were able to turn two Dolphin turnovers into only six points, but the bigger benefit may be the time of possession advantage as a result.
3:34 Miami responds quickly. Tagovailoa hits Tyreek Hill for a gain of 19, then on the next play goes over the top for a 45-yard touchdown. Hill had Charvarius Ward turned around.
Those were the first points scored on the 49ers defense in the second half in over a month.

3:43 San Francisco gets the ball across midfield but that’s it. The 49ers defense needs to step up now. Miami starts from its own ten.
3:56 It looked like that fourth down pass was incomplete. Kyle Shanahan with his second challenge of this possession.
3:58 The officials agree. 49ers take over at their own 36.
4:03 San Francisco is trying to run out the last six minutes of this game. Purdy with a three yard completion to Kittle to convert on third and short. Then Deebo Samuel takes a toss around the left side for 8.
Just now, Christian McCaffrey with a 30-yard gash all the way to the Miami 11.
4:08 What is Kyle Shanahan doing? The 49ers had the ball on the 11 and have lost 20 yards on three plays. George Kittle called for a hold on the last play.
4:10 Robbie Gould hits from 48 yards out. That’s the ballgame. 49ers 26 Dolphins 17
4:33 49ers win 33-17
