Jefferson Lerma suffered a broken nose from a punch in the face by Crystal Palace defender Joachim Andersen and Bournemouth boss Gary O'Neil insists he will demand answers over the situation from PGMOL chief Howard Webb.
The Cherries midfielder went down clutching his face in the 30th minute of the match at Selhurst Park on Saturday, which the hosts ended up winning 2-0.
However, the main talking point from the match has been an off-the-ball incident between Lerma and Palace defender Andersen.
The two players collide in the middle of the box, with the Danish defender appearing to extend a fist into the face of the Bournemouth midfielder.
