New video footage shows former NFL quarterback turned FOX Sports broadcaster Mark Sanchez behaving erratically and stumbling through the streets of Indianapolis prior to the incident in which he allegedly attacked an elderly man who stabbed him last weekend, TMZ Sports reports.

The footage shows Sanchez, 38, appearing to wander the area drunk, retracing his steps, leaning against a wall and breaking into interment bursts of jogging prior to the altercation with Perry Tole, 69, a grease truck driver, at around 12:30 a.m. local time last Saturday (October 4). Tole was seen pulling his truck into the alley at around 12:05 a.m. and Sanchez was walking unsteadily out of the alley at around 12:12 a.m.

Sanchez was seen walking down the sidewalk near the alley and then walking back in the opposite direction 90 seconds later. The broadcaster was then seen pausing and continuing to slowly walk down the street out of the camera's view before coming back and leaning against a wall at the alley's entrance about six minutes later.

A bystander was seen conversing with Sanchez prior to walking away, at which point the former quarterback walked down the alley toward the loading dock where Tole's truck was parked. Sanchez paused behind a dumpster before suddenly jogging toward the truck and out of camera view at around 12:25 a.m.

The footage then cuts to Sanchez clutching his chest after being stabbed by Tole, who police said was defending himself from a violent attack. Tole and his employer, FOX Sports, were listed as defendants in a lawsuit seeking compensation for the attack.

The lawsuit accuses Sanchez of appearing to be "intoxicated" when he "instigated an altercation" with Tole when the incident occurred in a loading bay in the alleyway. Tole claimed to have suffered “significant injuries to his head, jaw and neck” during the fight in which Sanchez slammed him to the ground, according to the lawsuit.

Authorities said Sanchez turned Tole's knife on him, which resulted in the elderly man being stabbed through the cheek and having his tongue cut. The lawsuit also claims that FOX Sports "knew or should have known" about Sanchez's "unfitness as an employee, propensity for drinking and/or harmful conduct" prior to the alleged incident.
