Officials postponed the Sugar Bowl, a major sporting event in New Orleans, on Wednesday night after a man drove his truck into a crowd of New Year’s revelers in what is being investigated as a terrorist attack.

The sold-out annual college football game will be moved to Thursday night, Allstate Sugar Bowl CEO Jeff Hundley said at a news conference.

Hundley said the decision was in the “best interest” of public safety.

Authorities said at least 15 people were killed and more than 30 others were injured around 3:15 a.m. Wednesday when a man intentionally rammed into a crowd of people on Bourbon Street, a popular destination in the city.

The suspect is dead, the FBI said. It identified him as Shamsud-Din Jabbar, 42, a U.S. citizen from Texas.

Notre Dame and the University of Georgia were scheduled to face each other in the “Sugar Bowl,” which has been played every year since 1935 at around 7:45 p.m. local time and is broadcast on ESPN.

Teams will take the field on Thursday at 3:00 p.m. local time (4:00 p.m. ET). Officials said there will be additional security measures.

In an earlier statement, Hundley said the Sugar Bowl committee was “devastated by the terrible events.”

“Our thoughts and prayers are with the victims and their families,” the statement said. “We are in ongoing discussions with local, state and federal authorities and will provide further details as they become available,” he said.

The University of Georgia Athletic Association said all team personnel and members of the official team travel party have been reported. “We are deeply saddened by the senseless violence that took place in New Orleans,” it said in a statement.
