JACKSONVILLE — Tom Brady trudged off the field with his helmet in one hand, grass stains on his jersey and a look of frustration on his face.

This was a different feeling for the New England Patriots quarterback — at least against Jacksonville.

Brady lost for the first time in nine starts against the Jaguars, a 31-20 setback Sunday in which Blake Bortles outshined the three-time league MVP and five-time Super Bowl champion.

Jacksonville had been the only remaining AFC team to never beat Brady. The Jags (2-0) finally got it done in a rematch of last season's AFC championship game.

It shouldn't take long for Brady and the Patriots (1-1) to bounce back. They play at winless Detroit Sunday.

"It's a long year," Brady said. "I think you have a bad day against a good team, it's a recipe for losing."

Brady completed 24 of 35 passes for 234 yards, with two touchdowns and a turnover. He was sacked twice, including once by former Gator Dante Fowler in the fourth quarter that caused a fumble. He said New England's offensive execution has room for improvement.

"I don't think it's anywhere near where we're capable of or what we've done at different points through a season," Brady said. "We've got to make improvements, and I think September and October, that's what they're for. I think there's a lot of practices we need and a lot of time that we need to figure out what we do well and what we don't do so well. But you have to try to win in the meantime. And today obviously wasn't enough."

The Jaguars, who can get to 3-0 for the first time since 2004 Sunday at home against Tennessee, did just about everything right.

They held tight end Rob Gronkowski to two catches for 15 yards. They slowed New England's running game to 3.4 yards a carry. They allowed just two plays longer than 25 yards.

And Bortles delivered the best game of his five-year career.

Bortles threw for 377 yards and four touchdowns. He tossed perfect passes in the end zone to Donte Moncrief, Keelan Cole and Austin Seferian-Jenkins in the first half, and then connected with Dede Westbrook on a short crossing route in the fourth quarter that Westbrook turned into a 61-yard score .

"We go against Blake in practice," Jaguars defensive end Calais Campbell said. "He has some days where he is just lights out and gets us. If he can get us, he can get anybody because we feel pretty good about ourselves. I know what's going to happen. If he keeps getting opportunities, he's going to be a big-time player.

"I was just grabbing popcorn every time the ball was in Bortles' hands. I say, 'He's going to do something great', and then he's running and spinning and, man, it was impressive."
