Giants’ Tyrone Tracy wants to prove that breakthrough isn’t a “one-time thing.”

What does Tyrone Tracy have in store for the encore?

After the Giants’ top offensive weapon, rookie receiver Malik Nabers, was sidelined with a concussion and running back Devin Singletary was sidelined with a groin injury, the Giants’ rookie running back had a career day against the Seahawks last Sunday.

He rushed for 129 yards on 18 carries, an average of 7.2 yards.

With Singletary listed as questionable for Sunday night’s game against the Bengals at MetLife Stadium, this could be another big game for Tracy.

“I want to prove that this is not a one-time thing,” Tracy told The Post on Friday. “I want to prove that I can go out and play another good game. I don’t really have any expectations based on my last game. “I approach every opportunity that comes my way with the same mindset, I’m just going to try to take full advantage of it.”

Giants left tackle Andrew Thomas praised Tracy’s performance against Seattle.

“He did a good job in a difficult environment because he mastered his key skills and could not only run the ball but also defend it,” Thomas said on Friday.

“He did really well, had a great game, kind of a coming out party,” Giants receiver Darius Slayton said Friday. “But of course it’s a week-to-week league so this week he’s got another chance to go out there and show what he’s got.

“We know what type of player he is, but every game is his own game. So you never know how it will manifest itself. I expect his talent to shine through this week like it did last week.”

In non-Nabers injury news, player Jamie Gillan appeared on the injury report on Friday with a hamstring issue that limited him in training and he is listed as questionable for Sunday’s game.

This brings back bad memories of Giants kicker Graham Gano, who appeared to be fine entering the game against Washington, but then appeared lame before the game, forcing the Giants to play the game without a kicker.

They lost 21-18 after having to rely on two-point conversions for touchdowns.

It is unknown whether the Giants will use an emergency player on Saturday if Gillan’s hamstring issue is not resolved.

Brian Daboll stated that CBs Adoree’ Jackson (calf) and Dru Phillips (calf and shoulder) are “doing well.”

He said the cornerbacks are “ahead of” Singletary, who is questionable, and said Friday that he is in a “gray area” regarding his availability.

WR Bryce Ford-Wheaton, who returned a blocked punt for a touchdown in Seattle on Sunday and did not practice on Thursday because of a shoulder injury, is considered questionable for the game.

Guard Jon Runyan Jr., who missed the last two days with illness, returned to practice Friday and is expected to play Sunday.

Playing will be DL DJ Davidson, who was listed as a limited participant on Thursday’s injury report with a shoulder injury.

LB Brian Burns (groin) was limited in practice but is expected to play Sunday.
