Mark Sanchez, a former NFL quarterback who now works as a TV analyst, was injured in a stabbing incident after supposedly attacking a worker delivering cooking oil at a hotel in Indianapolis. The incident is described by authorities as something that “never should have happened.”

Early on Sunday, prosecutors shared a probable cause affidavit providing details on the bizarre sequence of events that led to the 38-year-old former football star being stabbed and subsequently arrested.

The incident began shortly after 12:30 a.m. on Saturday when police arrived at Loughmiller’s Pub and Eatery in downtown Indianapolis. Upon arrival, they found Sanchez, 38, with multiple stab wounds to his upper body. Nearby, in an alley between two hotels, they also discovered a 69-year-old man with a cut on his left cheek.

Sanchez was quickly taken to a hospital by paramedics. When detectives attempted to gather a statement from him, Sanchez reportedly claimed that he only remembered “grabbing for a window.” He was unable to identify his assailant or the exact location of the stabbing.

Investigators reviewed footage from the incident, which apparently showed Sanchez approaching a large box truck. The victim, employed by a company dealing in commercial cooking oil and recycling, was in the middle of his work duties at the Westin.

According to the affidavit, Sanchez walked up to him and the two started talking. It appeared that the victim was then trying to get away from Sanchez, but the former first round pick allegedly started chasing the victim around the truck. Video allegedly shows Sanchez “grabbing and throwing” the victim toward a wall of the hotel. The two began to fight and Sanchez tossed the victim to the ground, the affidavit said.

Detectives spoke with the victim who gave a statement that matched the video, cops wrote. He said when Sanchez allegedly approached him and started talking, he leaned toward the ex-New York Jets QB because he was not wearing his hearing aids and could not hear him. He claimed Sanchez allegedly “smelled of alcohol and his speech was slurred.”

Sanchez told the victim he had “spoken to the manager of the hotel” who said the worker “could not be there,” the complaint stated. This allegedly confused the worker, who said he was going to call his manager. That’s when Sanchez allegedly entered the victim’s truck and kept repeating the claim that he couldn’t be there.

The victim knew at this time he “had a problem” and tried to grab his cell phone in the truck but Sanchez allegedly “blocked him from trying to call his manager.” The victim left his truck and tried to flag down a security officer at the Marriott, which is on the other side of the alley, before he walked on the passenger side of the truck. Sanchez again blocked the driver from going inside, cops alleged.

Sanchez “shoved” the victim who pulled out pepper spray and sprayed him in the face, per the complaint. It only stunned Sanchez for a brief moment who then attacked the victim again, cops said. The victim is identified as P.T. in the affidavit.

“P.T. thought ‘this guy is trying to kill me’ so he pulled his knife and when Mr. Sanchez came at him, P.T. went at Mr. Sanchez and struck him two or three times with the knife,” detectives wrote. “P.T. said he found himself flying back into the dumpster and falling onto the pallets on the ground.”

The victim said Sanchez continued his alleged assault and he “realized that he was in a life-or-death situation.”

He “somehow” made it to his feet when Sanchez allegedly came at him again and stabbed him one last time.

“The next thing P. T. knew was Mr. Sanchez looked at him with a look of shock, he slowly turned around, and Mr. Sanchez took off north bound in the alley.”

Cops later arrested Sanchez at the hospital. He stands accused of battery, unlawful entry to a motor vehicle and public intoxication. Sanchez was in town to call Sunday’s Indianapolis Colts game vs. the Las Vegas Raiders. He was reportedly last listed in stable condition and will be taken to jail once he’s released from the hospital.

“This incident should never have happened,” Marion County Prosecutor Ryan Mears said in a statement. “What began as a disagreement between a 38-year-old former professional athlete and a 69-year-old man should not have escalated into violence or left anyone seriously injured. As with any case, we will follow the facts and the law wherever they lead.”
