No Malik Nabers, maybe no Devin Singletary, no offense for the Giants? 

The Giants ruled out the dynamic rookie receiver Nabers (concussion) and listed the veteran running back Singletary (groin) as doubtful to play Sunday on the final injury report of the week.

That duo accounts for 55.5 percent of the team’s yardage and 83.3 percent (five out of six) of its touchdowns, which means others must fill a sizeable void to stay competitive against the high-scoring Seahawks. 

Nabers, who is not available to the media while in the concussion protocol under NFL rules, did not practice Friday and will not travel to Seattle. 

“He is making progress,” head coach Brian Daboll said, “but we’re going to do everything we can do to get him as healthy and right as we can. His safety, his well-being is first and foremost.” 

Singletary was limited in practice Friday, an upgrade from earlier in the week. Rookie Tyrone Tracy Jr., who has 12 carries through four games and fumbled on a kickoff return, is in line to start if Singletary is scratched. 

“If I feel like I’m comfortable enough to go, I’m going to go,” Singletary said. “Game day, game time, we’ll see.” 

Nabers leads the NFL with 52 targets, so where will quarterback Daniel Jones turn in his absence?

Jalin Hyatt is expected to fill the starting role, but perhaps Wan’Dale Robinson — whose 38 targets rank No. 8 despite playing alongside Nabers — will challenge Brandon Marshall’s NFL record of 28 targets in a single game. 

“Every week I go into looking at it like I can get a career high in targets,” Robinson said. “We have confidence in everybody, and I think Dabes is going to do a really good job of calling the plays to get some other guys involved. I never feel any pressure on myself to make it more than what it really is.” 

Darius Slayton, who has led the Giants in receiving yards in four of the past five seasons, could be asked to jump-start an offense that ranks No. 29 in the NFL in scoring (15 points per game). 

“Give me a chance to make some plays,” Slayton said. “However the game ends up going, whatever opportunities I get, I’ll do my best to maximize them.” 

The Seahawks have two Pro Bowl cornerbacks — Riq Woolen and Devon Witherspoon — and Witherspoon is versatile enough to face Slayton on the slot or Robinson in the slot. 

“I wouldn’t say we’ve gotten a bunch of double-teams with Malik,” Daboll said. “Seattle kind of plays a variety of coverages. How they’ll play us, I’m not sure. You watch the four games that they’ve played, and you base your game plan off what they’ve done.”
