The NFL decided not to sully the anniversary of “The Greatest Game Ever Played” with arguably the worst Giants team ever assembled. 

The Giants’ home finale against the Colts was one of five Week 17 possibilities to be flexed into three Saturday stand-alone television time slots, but the game will be played at 1 p.m. on Sunday, Dec. 29, as first reported by The Post. 

Had it been moved to Saturday, it would have been played on the 66th anniversary of the 1958 NFL Championship game between the Giants and Colts that is referred to as “The Greatest Game Ever Played.” 

That history would have been a nice touch in the Giants’ 100th anniversary season — if the season hadn’t gone horribly wrong. 

The Giants (2-12) will be playing Dec. 29 to avoid their second-ever winless record at home and trying not to become the first team in NFL history to go 0-9 at home (only four seasons of possibilities in the 17-game schedule era). 

The Giants have had banners paid for by fans demanding that owner John Mara make big changes and “fire everyone” fly over MetLife Stadium before each of their past two home games. 

If they lose Sunday to the Falcons in Atlanta, they will set a franchise record for the longest losing streak at 10 in a row. 

Tuesday was the deadline for the NFL to flex three games from Sunday to Saturday.

The final choices were Chargers-Patriots at 1 p.m., Broncos-Bengals at 4:30 p.m. and Cardinals-Rams at 8 p.m., while Falcons-Commanders was flexed into “Sunday Night Football.” 

At least one team in each of those four games is in the playoffs, which can’t be said for Giants-Colts after the Colts’ fourth-quarter nightmare in last Sunday’s loss to the Broncos. 

The Colts beat the Giants in the NFL’s first sudden-death overtime playoff game in 1958 at Yankee Stadium. 

Falcons head coach Raheem Morris declined Tuesday to name a starting quarterback for the Giants game, saying only that they need better production out of the position. 

That could be the first step to benching struggling $180 million free-agent signing Kirk Cousins after 14 starts and turning to rookie Michael Penix Jr., who was drafted No. 8 overall — two picks after the Giants passed to select receiver Malik Nabers. 

OT Jermaine Eluemunor hosted an event Tuesday night in conjunction with the Tom Coughlin Jay Fund Foundation. Fifty cancer patients (ages 10 to 17) received a $150 Target gift card, a catered dinner, event T-shirts and a personalized shopping experience with Eluemunor and teammates. 

The Jay Fund, started by former Giants head coach Tom Coughlin, provides financial and emotional support to families tackling cancer.
