The Jaguars did an excellent job keeping Reggie Bush under wraps for his first 11 carries Sunday. But on his 12th attempt, Bush showed why he remains a home run threat every time he touches the ball.

Midway through the third quarter, Bush charged through a gaping hole and dashed 53 yards before being wrestled to the ground, highlighting his 21-carry, 104-yard day.

“It was a power play, and I saw the defensive end and the D-tackle playing inside hard,” Bush said. “I couldn’t really see the outside ’backer when I jumped outside. Thankfully, he went inside, so it was pretty wide open.

“After that, it was just trying to make a play.”

Bush has made plenty of such plays in his two-year run in Miami. It was the seventh time he’s gone over 100 yards in a Dolphins uniform. But his contract expires after this season, and he said last week the Dolphins had not made any overtures to re-sign him.

So if Bush is headed to free agency, back-to-back 1,000-yard seasons would be a pretty strong bargaining chip. He needs to average just 58 yards over the next two games to make that happen.

“I think it would be pretty important,” Bush said. “I’m not going to say it wouldn’t feel good.”

Left hurting

The Dolphins entered the game with two starters ( Davone Bess and Koa Misi) sidelined by injuries. They left it with two more key contributors knocked out of commission.

Starting corner Nolan Carroll and short-yardage back Daniel Thomas both left with knee injuries, and neither returned.

Carroll’s injury was the most impactful. It forced R.J. Stanford into full-time duty, spelled only occasionally by Bryan McCann.

As for the players the Dolphins expected to be without, Marlon Moore started in place of Bess, and Jason Trusnik took Misi’s spot in the lineup.

Moore and Rishard Matthews combined for five catches and 56 yards. Armon Binns even got reps at receiver just six days after joining the team, but was not targeted once.

Bess and Misi joined quarterback Pat Devlin, offensive tackle Patrick Brown, tight ends Michael Egnew, tight end Kyle Miller and defensive tackle Kheeston Randall on the Dolphins’ inactive list.

Faked out

One of the very few Dolphins low points Sunday came in the second half, when they botched a fake field goal attempt, with holder Brandon Fields overthrowing Anthony Fasano by about 20 yards.

“I had him open, but the [Jaguars defender] kind of buzzed out there late and I was trying to put it high so Fasano would be the only one that had a chance at getting it, that turned into ten rows up.”

Added Dolphins coach Joe Philbin: “It was a play we didn’t execute well, obviously. …There were options [to audible out of it], or you could decide not to call it.”

This and that

• Actor Donald Sutherland and Man vs. Food’s Adam Richman were among the 53,667 on hand for Sunday’s game.

• The Dolphins held a moment of silence, flew flags at half-staff and had kids from Dolphins Academy on the field for the national anthem in honor of the victims of the Newtown, Conn., shooting.

•  The Dolphins have forced just one turnover in last seven games and have just 12 takeaways on the season. The team record for futility is 19 forced in a year.
