Tottenham star Eric Dier nearly went full-on Ron Artest in a game Wednesday -- charging at a fan in the stands who was allegedly talking trash about the player and his family.
The wild scene all went down during the Tottenham vs. Norwich City game in England ... where Hotspur star Dier had allegedly heard about some insults hurled his brother's way in the stands.
You can see in footage of the altercation ... 26-year-old Dier jogged along the sideline, jumped over the railing and beelined over more than a dozen rows of chairs to get to the fan to police everything himself.
