In two weeks, the Lions and Giants will hold joint practices in Allen Park, Mich., where Detroit linebacker Devon Kennard will be reunited with his former team for the first time.

Despite playing his first four years in New York, Kennard isn’t feeling the nostalgia.

“I’m going to see a lot of guys that I played with my whole career,” Kennard told reporters Wednesday, according to the Detroit Free Press. “But now I want to kill them. It’ll be all love when the pads are off. But when they’re on, it’s going to be go time.”

Not exactly. Kennard was asked about angling for Eli Manning, and the 2014 fifth-round draft pick laughed.

“Nah,” he said, “I’m pretty sure there won’t be any live hitting on Eli.”

Kennard was part of the purge this offseason, when a team coming off a 3-13 collapse let many of its veterans walk. Kennard started 35 games in four years — typically the starting middle linebacker when healthy — and amassed 9.5 total sacks.

As the Giants retooled, switching from a 4-3 defense to a 3-4, he signed with Detroit for three years and $18.75 million.

Thursday was a light day of practice for Saquon Barkley. But that’s part of the Giants’ plan to keep the rookie running back fresh. He watched approximately the final 45 minutes of practice from the sideline.

“He’s had a really, really big workload,” coach Pat Shurmur said. “This was the day, for no reason other than just [giving] a little bit less [work].”

For the second straight day, Landon Collins made an impressive play in coverage. After intercepting a tipped Manning pass and returning it for a touchdown on Wednesday, the Pro Bowl safety broke up a pass for Odell Beckham Jr. while in single coverage in an 11-on-11 red-zone drill on Thursday.

Eli Manning had a strong practice, which included connecting on a bomb to journeyman wide receiver Russell Shepard and hitting Sterling Shepard deep along the left sideline. His only pass that hit the ground came on a drop by running back Wayne Gallman.

The other quarterbacks, meanwhile, struggled. Backup Davis Webb was picked off by cornerback B.W. Webb and was off target most of the day while rookie Kyle Lauletta was intercepted by cornerback Kenneth Durden and fumbled a snap.

Jon Halapio bounced a snap to Manning out of the shotgun. This was noteworthy because of how infrequent it has happened through a week of practices for the converted guard. It’s a positive sign for the 27-year-old, who has received virtually all of the first-team reps, as he hopes to win the starting job.

CB Donte Deayon (hamstring) and S Curtis Riley (hamstring) remained out. LB Thurston Armbrister didn’t practice either and DL Dalvin Tomlinson rode the stationary bike on the side during the workout.
