Richie Incognito -- 'I'M MISUNDERSTOOD' ... I Just Wanna Play Football

Richie Incognito has issued another apology ... though it's unclear why ... and TMZ Sports has the video.

The embattled Miami Dolphins lineman was out in Beverly Hills this week -- with another hot blonde on his arm -- when he explained that he's a misunderstood guy who "just wants to play football."

"I'm misunderstood ... but you know what ... I apologize."

We're not really sure if he's apologizing for being misunderstood -- or apologizing for all of the things he allegedly did to Jonathan Martin -- but he seems to be sorry for something.

Know what he's not sorry about? Being a ladies man ... because the next night, he was hanging out with 5 GIRLS outside of a Hollywood nightclub.

Don't hate the player ...
