For that football dude Richie ... Incognito is more than just a name -- it's now a lifestyle.
Jay Glazer -- who interviewed the troubled NFL'er for FOX NFL Sunday's pre-game show -- tells TMZ Richie has not left his swanky hotel suite in Bev Hills since blowing into town Friday.
It's interesting ... Richie is not one to live on the downlow. If you have doubts about that check out the Ferrari he bought right after all the hazing stuff became public.
It seems Richie is feeling the heat or he's having a massive party in his room.
