England full-back Mike Brown has escaped a citing for his boot making contact with Conor Murray's head during Ireland's defeat at Twickenham on Saturday.

The Ireland scrum-half was left needing stitches under his eye as a result of the incident, but Brown insisted afterwards that the contact was accidental.

@dionwesty thank you! Video ref clearly showed I didn't and kicked the ball.

The Six Nations has now confirmed that Italian prop Martin Castrogiovanni is the only senior player who faces disciplinary action after the weekend's action after he was cited for an alleged stamp during his side's defeat to Scotland on Saturday.
