David Beckham has escaped punishment for an alleged elbow on Lee Bowyer during Manchester United's 1-0 defeat against Leeds on Saturday.
Match referee Jeff Winter saw the incident but did not book Beckham.
But the Football Association plans to investigate an incident in which Thierry Henry allegedly elbowed John Robinson during Arsenal's 3-0 win over Charlton.
The incident was not seen by referee Steve Dunn and the FA have decided to investigate further - which could mean referring the incident to the video advisory panel.
