West Bromwich Albion players turned on eachother after Cardiff City staged a stunning late comeback to draw 3-3 at the Hawthorns.
The Daily Mail says West Brom chairman Jeremy Peace has led an internal probe into a dressing-room dust-up that followed the club's 3-3 draw with relegation rivals Cardiff.
England Under 21 star Saido Berahino is believed to have been hurt when punches were thrown in a row about giving away an equaliser after six minutes of injury time.
Peace, director of football Richard Garlick and chief executive Mark Jenkins all stayed late into the evening at The Hawthorns on Saturday to sort out exactly what went on.
