The injury picked up to Manchester United midfielder Ander Herrera this past weekend could have been caused by referee Lee Mason, reports the Metro.
It appears, then, that the Spaniard - who signed for the Red Devils this past summer - collided with Mason during United's 2-1 victory over the Hammers on Saturday afternoon.
As Herrera attempted to sprint past Saturday's referee, it appears that the Spanish international made slight contact with Mason, which left him in pain around the rib area.
The midfielder was ultimately replaced minutes later, with it having been confirmed that he's fractured his rib, which could keep him on the sidelines for up to six weeks.
It hasn't been confirmed as to whether the coming together with Mason was the cause of the injury, but the vine is certainly causing some debate amongst the social media gurus.
It must be noted, however, that Herrera's injury is a major blow for the Red Devils as they go in search of back-to-back victories this weekend. Van Gaal's luck at Old Trafford hasn't been in of late, with as many as 11 players currently out on the sidelines through injury.
As well as Herrera, the likes of Michael Carrick, Chris Smalling, Jonny Evans and Co. are all out of action. United, then, will be down to the bare bones as they play host to Roberto Martinez's Everton side on Sunday.
United will also be missing captain Wayne Rooney after he picked up a three match suspension following his red card against West Ham United, but despite their problems they will still expect to secure all three points against the Toffees.
It's likely that vice captain Darren Fletcher will replace Herrera in the middle of the park alongside versatile Dutchman Daley Blind. Fans of the Red Devils will also be hoping that Phil Jones returns at the back, whilst Radamel Falcao and Robin van Persie are expected to lead the line in attack.
That could hand Juan Mata or Adnan Januzaj a start in the No.10 role on Sunday, with Argentine superstar Angel di Maria expected to feature once again.
