Michael Irvin is refiling his $100 million lawsuit against Marriott ... moving the matter to Arizona after receiving new details in the case, TMZ Sports has learned.
Our sources tell us ... after Marriott turned over the names of Irvin's accuser and others involved in the allegations against the former Dallas Cowboys star, Irvin's legal team filed a notice of dismissal for the case in Texas -- with the plan of refiling it in Arizona, the state where the alleged incident happened.
We're told Irvin's attorney, Levi McCathern, is set to have a news conference regarding the developments later Tuesday.
