DETROIT — Todd Bowles mixed things up with his starting offensive line on Saturday night.

The Jets head coach started Ben Ijalana at left tackle, Jonotthan Harrison at center and Brandon Shell at right tackle. Those three primarily had been on the second team in training camp, though Bowles has made it clear all three starting jobs are up for grabs.

“I said it was an even battle,” Bowles said. “So, the first week the other guys started. This week, they started. We’ll see what goes next week after watching the film.”

Those three played the first quarter while the usual starters — Kelvin Beachum at left tackle, Wes Johnson at center and Brent Qvale at right tackle — entered the game in the second quarter.

It was not a good night for the offensive line, which surrendered two sacks and failed to open many running holes for running back Bilal Powell in the 16-6 preseason loss to the Lions. The Jets averaged 2.2 yards per play in the opening half.

“I’m not worried about [the line play], but we need to fix it,” Bowles said.

The scoreboard showed the line failed.

“My initial feeling without watching film is that we didn’t have enough sustained drives and we didn’t do our part to help out the defense,” Ijalana said. “It took us awhile to get anything started. And, looking at the scoreboard, obviously we didn’t score any touchdowns.”

The Jets’ kicking competition may have gotten some clarity.

Ross Martin made field goals from 28 and 31 and missed a 56-yarder. Those were his first field goal attempts of the preseason, and lengthened his lead over Chandler Catanzaro for the kicking job.

Martin has outkicked Catanzaro in practice, but the Jets wanted to see how he handled kicks in games.

Catanzaro did not attempt a kick in the game. Catanzaro missed a 55-yard attempt in tghe preseason opener against the Titans.

The Jets are looking for returners, and did not find many answers.

Marcus Murphy had one nice kickoff return for 48 yards that was negated by a holding call on Josh Martin. But he also fumbled a kickoff. He was bailed out by an offside call on the Lions kickoff team that wiped out the play.

Frankie Hammond fumbled a punt return that the Lions recovered.

The Jets lost Lucky Whitehead to a broken foot this week. Whitehead was thought of as the favorite for the return jobs.

“We’ve got to catch the ball first and foremost,” Bowles said. “There’s too many penalties on special teams. I know there’s a lot of guys trying to prove themselves, but that’s got to clean itself up and we’ve got to tighten that ship next week and get the guys ready to play.”

Three of the Jets’ six penalties came on special teams.

Safety Rontez Miles left the game with a laceration under his eye and was tested for a concussion. … DL Anthony Johnson suffered a stinger.
