“Jackrabbit” should bounce back.

Janoris Jenkins, the Giants’ top cornerback, underwent a series of tests Monday to determine the severity of the back injury he suffered in Sunday’s win. Ben McAdoo said last night that those tests showed no structural damage or injuries to any internal organs.

“It was a nasty collision,” the coach said of Jenkins taking a knee to his back from teammate Trevin Wade. “We took every precaution we could afterwards and everything checked out. Right now it’s a painful bruised back.”

That’s not to say that Jenkins will be ready to play on Thursday against the Eagles. He did not practice Monday, and with a quick turnaround, Jenkins might miss the upcoming game. “It’s too early to tell,” McAdoo said.

Depending on the result of that game and others around the league, Jenkins conceivably could sit out the finale, too. It might be more prudent for the Giants to have him as close to full strength going into the playoffs rather than taking a risk.

Vereen hurt again

Shane Vereen likely is done for the rest of the season after re-injuring the torn triceps that landed him on injured reserve after Week 3 of the season. Vereen was designated to return from injured reserve and played in the last two games. He left early against Dallas with a concussion, then suffered the triceps setback against the Lions.

“It’s unfortunate,” McAdoo said. “He worked his tail off to get back to where he was. I’m disappointed for Shane.”

McAdoo said it is unclear whether Vereen will need another surgery on the injury.

Odell on Zeke: No fine?

Odell Beckham Jr. had an interesting take on the Cowboys’ Ezekiel Elliott jumping into a large Salvation Army kettle after his TD run and not getting fined. “That’s funny there’s no fine for that,” he wrote on Twitter. “I could only imagine if I was the one to do it. Just bein honest.”

Giant steps

The Giants’ chances of winning the NFC East title took a major hit on Sunday night when the first-place Cowboys beat the Bucs. That gave Dallas a two-game lead over the Giants with two games to play. “I wouldn’t say I was bummed,” said Eli Manning, who watched the game after the Giants’ 17-6 victory over the Lions. “I would’ve liked to see Tampa win, but I was excited about our win.” . . . McAdoo on the challenge of preparing for a Thursday game: “We’re going to stick and move . . . We can’t waste a second.”
