The Newcastle manager says the incident was one caused by frustration and passion.
Newcastle United manager Rafael Benitez has told reporters that he does not blame defender Daryl Janmaat over his self-inflicted hand injury, admitting that he can understand why "frustration" or "passion" would cause such an action, as quoed by the Shields Gazette.
Janmaat broke two fingers punching the dressing room wall in frustration after having limped off in the defeat to Southampton last weekend with a groin problem.
The Dutch full-back's actions were slammed by some fans and pundits incensed by the rash action at a time when the club desperately need all hands on deck in the fight to avoid relegation.
However, Benitez has admitted that he does not blame the 26-year-old for his reaction, and told reporters that he was chalking the incident down to it being merely an unorthodox manner of the player showing how much he cares about the club's situation.
The Spanish boss said, as quoted by the Shields Gazette: "Because he's injured we can't do anything, we've put out a statement saying clearly he can't play this game and we'll check the next one. He's ready to take the risk if he has to do it with his hand, but we still have to find a solution to his groin problem.
"Sometimes it's frustration, sometimes it's the passion. I had a player in the past at Real Madrid reserves with the same problem, sometimes they care so much and they want to be there, that can happen, obviously it's bad news.
"But if he's available for the next game, that will be a positive and maybe other players can put him under pressure."
Newcastle are in dire straits ahead of their home clash with Swansea City on Saturday, and know that they have reached the stage at which they simply must pick up three points.
With just six matches remaining, the Magpies are six points adrift of safety and with a worse goal difference than both Sunderland and Norwich City, albeit with a game in hand over the latter.
With at least one of those fellow strugglers certain to pick up at least a point from their meeting in Saturday's early match, it has become imperative that Benitez's side pick up a first win under the Spanish boss this weekend.
