• The Sugar Bowl was postponed by one day until Thursday following the attack on Bourbon Street in New Orleans, where the college football game will take place.
• A 42-year-old Texas man with an ISIS flag drove a pickup truck into a crowd celebrating New Year's Day in the French Quarter and then opened fire on police. At least 15 people were killed.
• The Sugar Bowl was set to be played in New Orleans' Superdome.

The Sugar Bowl was postponed one day until Thursday following the deadly attack in New Orleans.

The decision came hours after a 42-year-old man crashed a pickup truck into a crowd on Bourbon Street and then opened fire on police.

The district attorney of Orleans Parish confirmed Wednesday the game would be postponed.

The College Football Playoff quarterfinal game between Georgia and Notre Dame will take place on Thursday at 3 p.m. Central time at the Superdome, home of the NFL's New Orleans Saints.

The Caesars Superdome, an enclosed venue with more than 70,000 seats, was reportedly on lockdown following the attack. "It's in the best interest of everybody and public safety that we postpone," Jeff Hundley, Sugar Bowl committee CEO, reportedly said at a press conference on Wednesday.

The committee said in an emailed statement Wednesday that the law enforcement assets that typically would take part in an event of this magnitude had been instead engaged in the active investigations related to the attack.

"Our thoughts and prayers go out to the victims and their families as we work through this," said Hundley in an emailed statement late Wednesday. "We have full faith and confidence in the governor and the mayor and all the federal, state, and local first-responders that they've applied to this horrific event. Any time we have an event like the Sugar Bowl, public safety is paramount, and all parties involved agree that could only be achieved with a postponement. Now we will move ahead to take care of the details to make the Sugar Bowl the first-class, fun, and safe event that it has been for over 90 years."

The FBI identified the suspect in Wednesday's attack as Shamsud-Din Jabbar, a U.S. citizen from Texas, who plowed into a crowd, killing at least 15 and injuring 30 more. The FBI said in a statement that an ISIS flag was located in the pickup truck and they were "working to determine the subject's potential associations and affiliations with terrorist organizations."

Investigators reportedly found weapons and a potential explosive device in the vehicle, as well as other potential explosive devices in the French Quarter.

The Superdome is about 20 blocks from the attack, according to the Associated Press.

The stadium is also slated to host the NFL's 2025 Super Bowl in a little over a month.

"We are deeply saddened by the news of the devastating incident in New Orleans. Our thoughts are with the victims, the New Orleans community and all those affected," the NFL said in a statement on Thursday.

The league added that it, along with the local host committee, "have been working collaboratively with local, state and federal agencies the past two years and have developed comprehensive security plans." The NFL said the planning sessions would continue and it is "confident attendees will have a safe and enjoyable Super Bowl experience."
