Jets first-round pick Quinnen Williams had a quiet debut Sunday and left with an injury.

Williams, the No. 3 overall pick out of Alabama did not register a stat, then sustained an ankle injury that knocked him out of the game in the fourth quarter of the Jets’ 17-16 loss to the Bills on Sunday. Williams did deliver a strong blow to Bills center Mitch Morse on a play when Josh Allen ended up fumbling the snap.

“I think he did great out there today,” fellow defensive lineman Leonard Williams said. “The time he was out there, he definitely showed poise, showed that he knew what he was doing and also communicated well. That’s something you could see in a vet type of guy, when they’re communicating on the line, calling out offensive protections and stuff like that. You usually don’t see that in a young guy like that and he showed all of that today.”

Williams was one of two injuries the Jets suffered on defense late in Sunday’s 17-16 loss to Buffalo. Linebacker C.J. Mosley exited with a groin injury at the beginning of the fourth quarter and it was a critical turning point.

The injury occurred late in the third quarter when Mosley made a nice play in the end zone to deflect a pass away from Bills receiver John Brown.

“I’m all right right now,” Mosley said. “It hurts a little bit to plant, so that’s pretty much why I couldn’t go back in.”

Mosley said he plans on being back for Week 2 against the Browns.

The Jets defense had four takeaways in the first half, the first time they had four-plus in the opening half since Dec. 18, 2011, when they did that against the Eagles. … RB Le’Veon Bell’s opening 5-yard gain gave him 8,001 career yards from scrimmage in his 63rd game, the fasted NFL player to do that, beating out Eric Dickerson, who did it in 64 games. … WR Jamison Crowder’s 14 receptions matched a franchise record for most receptions by a wide receiver, initially set by Al Toon on Nov. 27, 1988, against the Dolphins. … RB Bilal Powell was inactive.
