() A prosecutor filed a felony charge against former NFL quarterback Mark Sanchez, who already faced misdemeanors for his involvement in a stabbing incident over the weekend.

Sanchez has been charged with one count of battery resulting in a serious violent injury, a Level 5 felony, according to local affiliate WXIN.

He was arrested Sunday after a late-night altercation with a 69-year-old box truck driver in downtown Indianapolis.

According to a probable cause affidavit obtained by WXIN, the driver told police that Sanchez, smelling of alcohol, approached his vehicle, attempted to climb into the cab multiple times and shoved him when he tried to get his cellphone from inside.

The driver, identified only as P.T. in the documents, told authorities he then pulled out pepper spray and a knife in self-defense.

The pepper spray “appeared to have an effect” on Sanchez momentarily, but the Fox Sports analyst wiped it from his face and continued approaching

The driver stabbed Sanchez several times and “found himself flying back into the dumpster,” according to court documents. After a final stab wound from the driver, Sanchez gave him a “look of shock,” turned around and left the alley.

The driver suffered a “severe laceration to the side of his face, penetrating all the way through his left cheek,” per court documents.

While in the hospital, Sanchez told police all he could remember was “grabbing for a window,” and that he had no clue who stabbed him or how it happened. Sanchez remains hospitalized as of Monday morning, WXIN’s Angela Ganote reported.

Marion County Prosecutor Ryan Mears announced the more serious charge at a press conference Monday, citing the victim’s age and injury severity as reasons for upgrading the accusation.

“This incident should never have happened,” said Marion County Prosecutor Ryan Mears. “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.”
