Artie Lange -- BANNED at ESPN After Slavery Sex Tweets

Artie Lange is persona non grata at ESPN after tweeting a slew of sexual and racially charged jokes about a female African-American ESPN host ... TMZ has learned.

Lange sparked outrage across the Internet Wednesday when he tweeted his graphic sexual fantasy about Cari Champion from "First Take" -- which involved her being a slave owned by Thomas Jefferson. Lange envisioned himself as Jefferson. 

ESPN initially called Lange's tweets "reprehensible," but now a spokesperson for the network tells TMZ they've flat out banned him. We're told ... "there will be no future bookings" for the comedian.

Late Wednesday evening Lange tweeted an apology directly to Champion -- but oddly added that he stood by the "joke" as a comedian.

Lange was also cut from a Comedy Central gig because of the slavery tweets.

Comedian and sometimes sports commentator Artie Lange is known for his unpredictable behavior, but yesterday he took to Twitter to share a very explicit fantasy he had about ESPN's "First Take" moderator and host, Cari Champion, and many believe he may have gone too far.

Lange detailed a fantasy where he is a slave owner and Champion is his slave, causing him to "get off" on the thought of her grabbing his whip and beating him.
