The Miami Dolphins’ backup quarterback plan of Skylar Thompson-Tyler Huntley-Tim Boyle has posted a 1-3 record in the absence of Tua Tagovailoa.

Perhaps Tagovailoa will return from concussion next Sunday in a home game against Arizona.

But is it too late?

Miami lost 16-10 at Indianapolis on Sunday afternoon.

The Dolphins are 2-4. The Colts are 4-3.

Dolphins quarterback quarterback Huntley was knocked out of the game with a shoulder injury in the third quarter, replaced by veteran Boyle.

He led a drive that could have tied the score at 13, but Jason Sanders hit an upright and missed a 54-yard field goal with about five minutes remaining.

The Dolphins’ special teams have been an embarrassment this season.

Miami ran the ball with some success (despite two lost fumbles).

Miami’s defense was solid, but once against yielded too many big rushing plays.

The game ended with Boyle threw an incomplete pass on fourth down with seven seconds remaining.

The pass was intended for Malik Washington around the Colts’ 20-yard-line.

Miami predictably pounded the rock

Entering the game, no team had given up more rushing yards than the Colts.

Without quarterback Tua Tagovailoa, it was extremely predictable that the Dolphins would pound the ball with De’Von Achane, Raheem Mostert and/or Jaylen Wright.

Achane, wearing a Guardian Cap for the first time, was impressive.

And Mostert was getting back into a groove, too. (A third-quarter fumble hurt.)

But Dolphins coach Mike McDaniel did the right thing. He fed his backs over and over and over in this one.

In the third quarter, McDaniel turned to the rookie Wright and he responded.

On back-to-back carries after Tim Boyle entered at quarterback for an injured Tyler Huntley, Wright ran right for 9 yards and up the middle for 19 yards.

Unfortunately for Miami, there were fumbles on back-to-back possessions in the third quarter.

First, Mostert fumbled. Then, fullback Alec Ingold fumbled.

Miami totaled 36 carries for 171 rushing yards through three quarters.

Tight end Jonnu Smith a positive factor

After a slow start to his Dolphins career, veteran tight end Jonnu Smith has become a factor.

It is clear that Huntley has a comfort level with Jonnu, who caught a first-quarter touchdown.

In fact, it was Jonnu and Jaylen Waddle who showed up to run routes for Huntley in Miami’s bye week.

It will be interesting to see if Jonnu continues to be a factor when Tagovailoa returns.

In the first half on Sunday, neither Tyreek Hill nor Waddle had a target. That will change when Tua returns.

Through three quarters, Hill and Waddle totaled 0 catches for 0 yards.

That they have maintained a certain measure of patience in Tua’s absence is notable.

Zach Sieler doing some Christian Wilkins-type things

Miami has had some spotty moments against the run this season, and did again on Sunday, but defensive tackle Zach Sieler has done his part to fill the void of departed friend Christian Wilkins.

Sieler recovered a fumble in the first half. And he continues to display a relentless that helps set a tone for the entire defense. He’s stepped up his leadership role, too.

Because veteran Calais Campbell has tapped into a Fountain of Youth in South Florida, the combination of Sieler and Campbell has been impressive.

In fact, one could argue last year’s Wilkins-Sieler is this year’s Sieler-Campbell.

Campbell, who is playing inside and outside, had a tackle for loss to open the game — again.

Miami’s defense sold under Anthony Weaver

The Dolphins’ first-year defensive coordinator, Anthony Weaver, has done a fine job.

Yes, the schedule is going to get tougher.

But Weaver has installed a multiple defense that dominates on third downs.

Miami has been able to create some pressure, even without Bradley Chubb and Jaelan Phillips.

And Miami’s pass defense, even when missing a starting safety or two, has been excellent.

We get it. Slowing down Anthony Richardson in the air is not close to the type of challenge Miami may face in future weeks.

Here are some of those quarterbacks they figure to play: Kyler Murray, Josh Allen, Matthew Stafford, Jordan Love, Aaron Rodgers (twice), C.J. Stroud, Brock Purdy. So, yes, it will get tougher from here.

Concerns will probably shift from run defense to pass defense in future weeks. The Dolphins allowed the Colts to rush for more than 150 yards on Sunday.

But Weaver seems to have the ability to make some good adjustments and come up with some reasonable solutions.

Miami’s defense, and its defensive coordinator, do not appear to be a problem.
