Rams Told Eric Dickerson He's Not Wanted at Games

4:31PM PT -- Rams C.O.O. Kevin Demoff says Eric Dickerson is NOT banned from the sideline ... and is welcome at Rams games/practice. Demoff says he has reached out to E.D. in an effort to clear up any miscommunication.

Eric Dickerson says he's persona non grata on the L.A. Rams sidelines -- and it's all over criticisms the NFL great made about the team.

The Hall of Famer went on his radio show on AM 570 LA Sports early Monday and said, "Someone with the Rams told me I'm not wanted on sidelines at games, that what I've said makes the players uncomfortable."

Dickerson did not reveal who made the call -- but sources connected to the situation say it was someone powerful.

Dickerson said the Rams official told him his honesty was making players uncomfortable.

We're told Dickerson is unhappy with the situation -- especially because he's not only been a supporter, but hosted the rookies at his home during training camp in his own "rookie symposium."

We reached out to the Rams -- so far, no word back.
