EAST RUTHERFORD, N.J. – The Giants will play without their top receiver for the second straight week but have a chance to get their top rusher back when they host the Cincinnati Bengals Sunday night in MetLife Stadium.

Rookie wideout Malik Nabers remains in the NFL concussion protocol and has been declared out of the game. He did not play in the Giants' 29-20 victory last week in Seattle. The team's first-round draft choice this year, Nabers leads the Giants with 35 catches, 386 yards, and three touchdowns.

Nabers was hurt in the Giants' game against Dallas on Sept. 26.

"It was a pretty big hit," coach Brian Daboll said. "I'm not going to get into what it was, but it was certainly a big hit."

Outside linebacker Kayvon Thibodeaux will also not play after suffering a wrist injury against the Seahawks that required surgery this week.

Running back Devin Singletary, who has run for a team-high 221 yards and has both of the Giants' rushing touchdowns, is questionable because of the groin injury that sidelined him last week. He was listed as doubtful last week before becoming a gameday inactive. Singletary was limited in practice the last three days.

Wide receiver/special teamer Bryce Ford-Wheaton (shoulder) and punter Jamie Gillan (hamstring) are also questionable. Ford-Wheaton did not practice yesterday but worked on a limited basis today. Gilan was added to the injury report with tightness in his left (kicking) hamstring.

Coach Brian Daboll was asked about only injuries at his pre-practice news conference, starting with Nabers.

"He'll be doing stuff out on the field," Daboll said. "More like he was doing the last two days. He won't make it (the game)."

Daboll was questioned how Nabers can advance though the protocol.

"There's a communication between him and the training staff, and then he'll do activity, and then there's communication after that," Daboll said. "And we're still, obviously, we're making progress but again, that's never anything you want to rush."

Daboll declined to discuss whether Nabers has symptoms or why he hasn't advanced further in the protocol.

"I'll leave that in-house," Daboll said. "But making progress. He'll do some more than he did yesterday, similar to probably the day before. Take it day by day."

The Giants were able to gain a season-high 420 yards last week without Nabers and Singletary. Rookie Tyrone Tracy rushed for 129 yards on 18 carries, a 7.2-yard average that was the highest by a Giants rookie with that many carries since Dec. 3, 1950, when Eddie Price averaged 8.7 yards (18 attempts for 156 yards).

Tracy said Singletary has become a mentor – "literally anything I ask him, he's always there to help" – but he would like to maintain a heavy workload.

"When I'm out there on the football field, obviously I want opportunities," Tracy said. "But with how the past Sunday went, hopefully I'll be able to get more (and) building the trust with my team, my teammates and then also the coaching staff.

"I always have confidence. No matter how good a game I have or how bad a game I have, I'm always going to have confidence."

While Tracy took charge of the rushing attack, Darius Slayton stepped up in the passing game with eight catches for 122 yards, including a 30-yard touchdown.

"I think Malik is a great player," right guard Greg Van Roten said. "We saw that early and we were definitely going to miss him. But this is the NFL and it's cliche, but it's next man up and everyone's got a role. I was happy that Slay had the game that he had, that was good for us that he could step up like that. And then Tracy had a great game.

"We have good football players and we're not worried when someone goes down because we know the depth we have. And that's incredibly valuable as the season goes on, because 17 games in a brutal sport and we know we have talent."

*Daboll said no decision has been made about Thibodeaux going on injured reserve. If the Giants make that move, Thibodeaux would miss a minimum of four games.

"There's a possibility," Daboll said. "Got to see where we're at here after practice. … I'm taking it day by day here or week to week, like I said. We'll cross that bridge when we get to it."

*Guard Jon Runyan returned to practice after missing two days due to illness.
