Did Marouane Fellaini headbutt Claudio Yacob in Manchester United's goalless draw with West Brom?
The incident occured in stoppage time of a frustrating afternoon for United, who drew for the eighth time at home in the Premier League this season.
Yacob and Fellaini were involved in a tangle of legs in midfield, along with Wayne Rooney, and tempers became frayed.
As the referee brought the play back for a foul by Rooney, Yacob and Fellaini went head-to-head.
Fellaini does have previous when it comes to using his head.
In 2012 he was banned for three matches after accepting a violent conduct charge issued by the Football Association for headbutting Stoke City's Ryan Shawcross in Everton's 1-1 draw at the Britannia Stadium.
Fellaini will not face any retrospective punishment this time as referee Mike Dean spotted the incident and booked both Fellaini and Rooney.
But should it have been a red card?
