Lions 16, Jets 6

Matthew Stafford threw a 5-yard touchdown pass to Marvin Jones in the second quarter, and Detroit shut down Christian Hackenberg and the New York Jets in a preseason game Saturday night.

After losing defensive lineman Kerry Hyder to an Achilles tendon injury in their preseason opener at Indianapolis, the Lions were still able to pressure Hackenberg early on. The Jets managed only 3 yards of offense in the first quarter and just two first downs in the first half.

Jets quarterback Josh McCown sat out this game, but Hackenberg did little to impress in his absence. Hackenberg was 2 of 6 for 14 yards and was sacked twice.

Stafford went 8 of 10 for 84 yards.

Matt Prater kicked field goals of 37 and 25 yards in the first half, and his 50-yarder with 1:11 left in the fourth quarter put the Lions up 16-6.

Detroit's depth along the defensive front is being tested because of injuries to Hyder and Ziggy Ansah, but the Lions looked fine in this game. On the very first series, Cornelius Washington came in unblocked and sacked Hackenberg, forcing a fumble that the Jets were able to recover.

Detroit's Akeem Spence added a sack later in the first quarter. New York finished the half with minus-3 net yards passing.

With Matt Forte still recovering from a hamstring injury, Bilal Powell had nine carries for 32 yards for the Jets.

Stafford was fairly sharp for the Lions, but they managed only one touchdown. Jones made a nice catch in the back corner of the end zone and held on amid tight coverage from Morris Claiborne to put Detroit up 10-0.

Ross Martin made field goals of 31 and 28 yards in the fourth quarter for the Jets, but he missed from 56 in the third.

Notes

Seahawks LT George Fant suffers torn ACL in right knee

Seahawks left tackle George Fant suffered a torn ACL in his right knee in Friday night's preseason game against Minnesota and is likely done for the season.

Seattle coach Pete Carroll said after the 20-13 victory that Fant has a significant injury that will require surgery.

"It's heartbreaking. It's so unfortunate for George," Carroll said. "There are other things that follow that but my first thoughts are for George."

Fant, the presumptive starter going into the regular season, was hurt midway through the second quarter of Friday's game against the Vikings. Fant was rolled into by teammate Justin Britt on a pass play and immediately fell to the turf in pain. The team training staff attended to Fant on the field and placed an air splint around his lower right leg before he was taken away on a cart.

Fant took over at left tackle midway through last season and spent the offseason reshaping his body to be stronger going into this season. Earlier this week offensive line coach Tom Cable said Seattle was set on the left side of the offensive line with Fant at tackle and Luke Joeckel at guard.

"He's going to take the same approach that he took to this past offseason and he's going to get back and when he gets back he's going to be a really good football player," Carroll said.

Dolphins sign Maualuga

Linebacker Rey Maualuga has signed with the Miami Dolphins, who put wide receiver Isaiah Ford on injured reserve.

Maualuga gives the Dolphins some needed linebacker depth, especially after rookie Raekwon McMillan was lost for the season with a knee injury in Miami's first preseason game.

Maualuga played his first eight NFL seasons in Cincinnati, which cut him back in March. He was a full-time starter for the Bengals in his first seven seasons, then started only six games last season.

Ford was Miami's seventh-round pick in this year's draft out of Virginia Tech.

Jaguars waiting on QB decision

Jacksonville Jaguars coach Doug Marrone isn't quite ready to name Chad Henne his starting quarterback.

Or Blake Bortles, for that matter.

Marrone said Saturday he wants to "see how this thing goes" over the next few days before deciding who will start against the Carolina Panthers in a preseason game Thursday night.

Marrone opened up the team's quarterback competition after another inconsistent performance from Bortles, the third overall pick in the 2014 NFL draft.

"I'm going to watch during the week and not put myself into a situation where you kind of get backed up and at the end of the day you've got to change it," Marrone said. "That's the worst thing you can do. So you just go out there and say, 'Hey, this is what we're going to do during the week. We're going to see how this thing goes.'"

Bortles was 8 of 13 for 65 yards in a loss to Tampa Bay. All four of Bortles' drives ended with punts. Bortles has led the offense to three points in six possessions in the preseason.

Henne is 11-of-16 passing for 183 yards, with a touchdown. The 10th-year pro should have another score, but rookie Keelan Cole dropped a would-be touchdown pass in the second quarter against the Buccaneers.

Marrone said Bortles and Henne split starter repetitions Saturday.

"You have to be able to make a decision, and you don't want to get yourself into a point where you make too quick of a decision," Marrone said. "So, at the end of the day, I think you just have to evaluate it and make a decision what's best for the team moving forward. Like I said before, it's very simple. I'm just looking to see who can lead from that position."

Bortles had been the franchise's unquestioned starter for nearly three years. Even Marrone and the team's top decision-maker, Tom Coughlin, backed Bortles all season.

The biggest question now is whether the Jaguars can even stick with Bortles. Marrone and Coughlin clearly have concerns about his ability, and benching him could be another blow to his confidence. Plus, the team picked up the fifth-year option in his rookie contract and could be on the hook to pay him $19 million in 2018 if he sustains a significant injury this season.

Regardless, the Jaguars are hoping demoting Bortles prompts him to play better.

"You don't make it this far if you're not a competitor," veteran tight end Marcedes Lewis said. "If you're a competitor, you're going to respond to it like you should and make it very, very hard for the people up there making the decisions."

Marrone said he has not been part of any conversations about bringing in another quarterback. The Jaguars also have second-year pro Brandon Allen on the roster.

For now, the competition is between Henne and Bortles.

"That's the situation in which coach felt like he needed to do something," receiver Marqise Lee said. "That's the situation that the quarterbacks got to handle. ... As far as making decisions like that, it's not my job. I'm going to sit back and wait. At the end of the day, I believe in all three quarterbacks and having a possibility to come out and doing the things that we need to do in order to get the Jaguars going."
