INDIANAPOLIS — Several sources, including ESPN and TMZ, have indicated that former NFL quarterback Mark Sanchez has been seriously injured in a stabbing in downtown Indianapolis early Saturday morning.

According to information obtained by FOX59/CBS4, the individual who allegedly stabbed Sanchez is claiming self-defense while calling the former NFL quarterback the aggressor in the encounter.

According to the Indianapolis Metropolitan Police Department, just after 12:30 a.m., officers responded to the 300 block of W. Washington Street on the report of a person shot. When police arrived, they found one person stabbed and another injured.

According to IMPD, a physical disturbance happened that involved two males with one man receiving “lacerations” and the other sustaining injuries consistent with stab wounds.

Both individuals involved in the incident are not local residents, IMPD said, but the police department abstained from releasing any further information about their identities at this time.

FOX59/CBS4 obtained additional information about the incident, however, including the account of the individual involved in the stabbing incident with Sanchez.

According to this source, the stabbing took place near Loughmiller’s Pub & Eatery. Sanchez was allegedly stabbed in the chest, taken to the hospital for surgery, and is the individual listed as being in critical condition by police, sources say.

The second individual also reportedly had “significant injuries” and claimed Sanchez was the aggressor in the incident and that he was merely defending himself with a knife.

According to FOX59/CBS4 sources, Sanchez wasn’t cooperative with responding police officers.

The second individual involved in the incident reportedly told police he was making a food delivery when Sanchez told him to leave and that he couldn’t park in the alley. The victim claimed Sanchez became aggressive and used pepper spray. This is when the individual claimed to stab Sancehz in self-defense.

It is important to note that FOX59/CBS4 sources said that Sanchez has not yet given his account of how events unfolded.

Both Sanchez and the other victim were transported to hospitals.

Sanchez was scheduled to broadcast the Colts vs. Raiders game at Lucas Oil Stadium with FOX Sports on Sunday.

Sanchez, a 38-year-old former New York Jets quarterback, starred at USC from 2005-2008 and was selected 5th overall by the Jets in the 2009 NFL Draft.

FOX59/CBS4 reached out to FOX Sports, who responded with the following statement.

Mark Sanchez was injured in Indianapolis on Saturday and is currently recovering in the hospital in stable condition. We are deeply grateful to the medical team for their exceptional care and support. Our thoughts and prayers are with Mark, and we ask that everyone please respect his and his family’s privacy during this time.
