James McClean has posted a gruesome picture on Instagram of an injury picked up against Liverpool on Saturday.
Jurgen Klopp's side picked up a deserved 2-1 win and would have been top of the table heading into Sunday had Gareth McAuley not grabbed a late consolation goal.
But McClean, who was substituted off just past the hour mark, has appeared to hit out at referee Neil Swarbrick for not punishing a Liverpool player after sustaining a pretty horrific wound.
There was a spot of blood visible on the Republic of Ireland winger's sock and he didn't look in too much discomfort as he exited the field of play but the true extent of his injury has now been revealed.
He took to Instagram to post an image of a gigantic gash on the side of his leg. You can see the post if you scroll down, however, you should be warned: GRAPHIC CONTENT BELOW.
The picture was accompanied by the caption: "If it was vice-versa" - hinting that if McClean had left such a mark on a Liverpool player, he might have been given his marching orders.
The strangest thing about the incident, though, is that no one appears to know who actually inflicted the injury.
Despite the depth of the wound, it doesn't look like McClean will be out of action for too long and he could potentially still be in contention to face Manchester City on Saturday.
Before the defeat last weekend, the Baggies were on a four-match unbeaten streak - including three consecutive 1-1 draws - and they now sit three points above the relegation zone after nine games.
