JACKSONVILLE – Maybe the Mania is back.

Jaguars rookie quarterback Gardner Minshew II, whose early-season success sparked "Minshew Mania" both locally and nationally, turned in the best game of his brief NFL career Sunday. The result?

A 29-15 victory over the New York Jets in front of 57,833 at TIAA Bank Field.

Minshew threw three touchdown passes – two in the first quarter and another in the fourth to secure the victory – and the Jaguars' defense complemented the performance in dominant fashion with eight sacks and three key interceptions.

Minshew and the defense were both critical in the game's key sequence, with cornerback A.J. Bouye intercepting a pass from Jets quarterback Sam Darnold with the Jaguars leading by a touchdown midway through the fourth quarter. Bouye returned the deep pass to the Jets 24.

Minshew, who completed 22 of 34 passes for 279 yards and three touchdowns with no interceptions Sunday, capped the short drive by scrambling on third-and-goal and completing an eight-yard touchdown pass to wide receiver D.J. Chark Jr.

That gave the Jaguars a 29-15 lead with 4:13 remaining.

Wide receiver Chris Conley caught four passes for a career-high 103 yards and a touchdown, and Chark caught six passes for 79 yards and a touchdown.

Running back Leonard Fournette rushed for 76 yards on 19 carries; he had rushed for more than 100 yards in three of his past four games.

The Jaguars are 4-4 after their second consecutive victory. The Jets are 1-6.

Jaguars defensive ends Yannick Ngakoue and Josh Allen both registered two sacks Sunday, with safety Ronnie Harrison and defensive end Dawuane Smoot both registering one. Defensive end Calais Campbell had a solo sack and shared one with defensive tackle Abry Jones early in the third quarter. 

Cornerback Tre Herndon intercepted Darnold in the first quarter and fourth quarters, with the first leading to a 70-yard touchdown pass from Minshew to wide receiver Chris Conley and the second securing the victory with just under four minutes remaining.

Darnold completed 21 of 30 passes for 218 yards and two touchdowns with three interceptions. Jets running back Le'Veon Bell rushed for 23 yards on nine carries.

Step by step: 

*The Jaguars took a 6-0 lead with a six-yard pass from Minshew to wide receiver Keelan Cole with 12:39 remaining in the first quarter; Fournette's 66-yard run set up the touchdown, which was the second touchdown reception for Cole in as many weeks. The Jets took a 7-6 lead on the ensuing possession when tight end Ryan Tucker turned a short pass into a 24-yard touchdown reception with 4:51 remaining in the quarter; the Jets drove 93 yards on 12 plays on the possession, with Darnold completing seven of seven passes for 88 yards. Conley's 70-yard reception on a pass from Minshew gave the Jaguars a 13-7 lead with 1:11 remaining in the quarter.

*The Jaguars pushed the lead to 16-7 with 2:57 remaining in the second quarter with a 29-yard field goal by kicker Josh Lambo, a play that capped a 17-play, 84-yard drive that consumed 8:56. The Jaguars earlier in the quarter squandered a chance to take a two-possession lead when Minshew lost a fumble that Jets linebacker Blake Cashman recovered at the Jets 37; it was the fourth lost fumble in three games for Minshew. The Jaguars pushed the lead to two touchdowns with a 43-yard field goal by Lambo with :19 remaining in the half.

*The Jaguars again controlled momentum in the third quarter, sacking Darnold three times and taking a 22-7 lead when Lambo converted from 24 yards with 2:11 remaining in the quarter.

*The Jets cut the Jaguars' lead to 22-15 with 13:07 remaining when Darnold passed three yards to Griffin and followed that with a two-point conversion pass to Griffin.
