6) Nico Rosberg (Formula One)
Mercedes' driver Nico Rosberg deliberately crashed his teammate's Lewis Hamilton's car during Belgian Grand Prix, as claimed by Hamilton himself.
His race was effectively ended when he suffered a puncture on lap two after Rosberg collided with him.
They had a meeting together in which Rosberg admitted that he did that on purpose. He could have avoided that but he didn't want to and did it to prove a point.
Mercedes Formula 1 boss Toto Wolff also said the incident was "absolutely unacceptable" and blamed Rosberg for causing it.
7) Jesse Ryder (cricket)
In the month of February during India's tour to New Zealand, the Kiwi opener was indulged in a fight with his teammate Doug Bracewell. On the eve of first test i.e. 5th February Jesse Ryder and the bowling all-rounder Doug Bracewell went for a late night drinking session at Auckland Bar. The two players then got injured after a physical altercation with each other.
Both the players though admitted to being at the incident, but were dropped from the selection for the second test against India.
Last year in March after getting drunken late night in a bar, he was attacked by a group of youths and suffered a fractured skull and a collapsed lung. He went into koma but gained his consciousness soon.
