A month after Mark Sanchez was involved in a near-fatal fight while in Indianapolis to call an NFL game for FOX, the company has handed the quarterback-turned-broadcaster his pink slip, TMZ Sports has learned.
A FOX Sports spokesperson tells us ... "We can confirm that Mark Sanchez is no longer with the network. There will be no further comment at this time."

We broke the story in early October -- Sanchez, in town to call the Colts vs. Raiders football game, was involved in a bizarre altercation where he allegedly attacked a 69-year-old delivery driver .
