The Detroit Lions had to break out the injury cart Tuesday at training camp.

In full team drills, defensive lineman John Cominsky was carted off the field after he suffered a right knee injury. Cominsky was playing at defensive end and crashed inward to fill the A-gap on a draw up the middle by Jermar Jefferson. Jefferson was wrapped up from behind by undrafted free agent David Bada and the pile of bodies fell forward into the back of Cominsky's leg.

Cominsky stayed on the ground for a few minutes while being tended by trainers and talking to other defensive linemen before a cart took him off the field.

The second day of padded practice led to a few other nicks and bruises. Rookie cornerback Ennis Rakestraw and safety C.J. Moore also briefly left drills to work with trainers for a couple of minutes before re-joining practice and finishing with the team.

Cominsky's injury happened on the Lions' second day of padded practice in training camp where head coach Dan Campbell expected a more intense and longer practice than Monday. NFL Network reported later on Tuesday that Cominsky's injury is a torn MCL that requires surgery and will sideline him for most of the season.

Elsewhere on the injury front, defensive back Brian Branch went through walkthroughs and some team drills before resuming his individual work with trainers as he ramps up from his offseason ankle surgery.

"There's an urgency and I would expect it to step up today another notch," Campbell said before practice. "It'll be a more aggressive day, a little longer, and guys to really go out there and compete."

Defense gets into turnover column

Not that the offense was bragging, but the defense hadn’t picked off a pass during training camp heading into Tuesday’s practice. Rakestraw, the rookie cornerback, broke the five-practice streak late Tuesday morning, when he sat down in the back middle of the defense and waited for a Hendon Hooker pass to hit him in the gut.

The rookie barely had to move. Still, he was in a smart position, and if Hooker saw him, he didn’t see him quickly enough.

The second-year quarterback struggled Tuesday in the full-team portion of the scrimmages. He held on to the ball too long at times and appears unsure when to leave the pocket.

His second interception came when he felt rushed on a corner blitz. Loren Strickland hauled in the easy money.

Remember, this is Hooker’s first training camp, after missing last year's recovering from a serious knee injury suffered at Tennessee. He is essentially a rookie, and while he struggles some with timing, decision-making, vision and accuracy, he also makes plays, whether he is taking snaps with the third team, as he did Tuesday, or the second team, as he’s done occasionally, rotating with Nate Sudfeld.

The first team, meanwhile, finally gave up a pick, too, when Jared Goff tried to go deep down the middle — shading left — and didn’t see Derrick Barnes hiding underneath. Barnes is fighting for time at linebacker with Jack Campbell.

He is not going to make the decision easy for Aaron Glenn and his staff. He’s been making plays since camp started.

So have the defensive backs, who’ve been noticeably shrinking the field since camp began. They just hadn’t taken the ball, even when they had chances.

“Getting the ball? That’s what it's all about,” said Amik Robertson, the slot back who missed an opportunity for a pick Monday.

Davenport working into form

Defensive end Marcus Davenport said the ankle injury that kept him out of the final 13 games of the 2023 regular season as a member of the Minnesota Vikings is not limiting him in training camp as he works to find his form again.

Davenport, a former first-round pick for the Saints who signed a one-year deal with Detroit in free agency, has prototypical defensive end size at 6 feet 5 and 265 pounds and has shown an ability to win in a variety of ways from spots along the defensive line.

Playing from the right end in practice, Davenport blew around the edge of left tackle Dan Skipper before stopping just short of Sudfeld, wearing the red no-touch jersey. He had consistent battles with Penei Sewell and the freshly extended Taylor Decker, going up against the first-team offense where he could sharpen himself against some of the best linemen in the NFL.

"I'm kicking some rust off, but I have good teammates to go against, so that has definitely helped," Davenport said.

During position drills, Davenport mainly worked with the other edge rushers who lined up with a hand in the dirt but also took a few snaps with the strongside linebackers working to drop into zone coverage before returning up front. He is happy with what he's seeing from his teammates in the trenches.

"We got a lot of ballplayers," Davenport said. "We got a lot of names that are not being said and appreciated. But, I think it's definitely been a driving force that we have good competition."
