In his last game, Jabrill Peppers notched a season-high 10 tackles. In the previous game, he forced a fumble at the goal line. The game before that, he returned an interception for a touchdown and had two passes defensed.

But the Giants safety is far from pleased with his play.

“I’m missing too many easy tackles, man,” Peppers said Thursday after practice. “It’s just me being overly aggressive. It’s a cut-back league, so I just to keep that in mind.”

One play in particular stood out against the Patriots. After the Giants had rallied to get even at 14 late in the second quarter, Peppers had a chance to force a punt following a dump-off to James White, but he missed the tackle. New England scored a touchdown on the drive.

The week before, he missed a crucial tackle on Vikings receiver Stefon Diggs.

“Discipline, I just got to slow down,” Peppers said. “I’ve been the culprit on a lot of play-action passes. Some of them were big plays, some of them weren’t. I just know I like to play as clean a game as I possibly can to help the team.

“Don’t let it keep showing up on tape, so that’s my mindset right now. I’m been making that a point of emphasis. Sunday is the only day you really get to go out there and hit somebody. So that’s what I’m most looking forward to.”

Saquon Barkley isn’t the only Giants running back getting healthier. Wayne Gallman (concussion) practiced fully Thursday for the first time since suffering the injury in a loss to the Vikings on Oct. 6. However, he remains in the concussion protocol, as does defensive lineman Olsen Pierre, who also practiced fully. The next step for both players is getting cleared by an independent neurological doctor.

Wide receiver Sterling Shepard was limited and remains in the protocol. Cornerback Corey Ballentine (concussion) didn’t practice. Tight end Evan Engram (knee) practiced fully for the second straight day and seems likely to play.

With Ballentine out, the Giants have to find a new kickoff returner. Receivers Cody Latimer and Darius Slayton, along with Peppers, are three options, special teams coordinator Thomas McGaughey said. A rookie, Slayton has never returned kicks before, but his speed makes him an intriguing possibility.

“He’s been catching punts and kicks every day for the last three months,” McGaughey said. “Just hopefully that work will pay off in the game.”
