Michael Irvin was back analyzing games on the NFL Network on Sunday ... after he settled his $100 million defamation lawsuit against Marriott.
The Dallas Cowboys legend was all smiles on "NFL Gameday Morning" as he was introduced by host Rich Eisen ... saying on the show, "It's good to be here."
The appearance marked the first time Irvin had been on the network since February ... after he had been suspended following allegations that he was inappropriate with a Marriott employee during Super Bowl week in Phoenix.
