Richie Incognito calls Jonathan Martin his best friend on the Miami Dolphins -- and says he's worried about him ... even though Martin's allegations of hazing got Richie suspended ... TMZ has learned.
Incognito talked today for the first time about the scandal ... with FOX NFL insider Jay Glazer. Sources on the FOX set tell us Incognito wasn't exactly apologetic for his actions -- but instead expressed deep concern about Martin's health since he left the team.
We're told Incognito was willing to answer any and all questions about the controversy -- including alleged threats against Martin's family, and the infamous voicemail he left ... where he allegedly called Martin a "half n***a."
