Wakefield full back Richie Mathers has undergone surgery on a ruptured testicle.
Mathers, 29, sustained the injury in Sunday’s 44-24 defeat at Wigan.
He said: “Darrell Goulding‘s knee caught my right testicle by accident and I felt it all the first half, although it wasn’t excruciating.
“I then went over on my foot and came off with that. I literally stayed up all night icing my foot and I was like a zombie when I went to training yesterday.
“It was only when I went for a shower that I noticed the testicle had swollen a fair bit and I showed it to the doctor, who sent me straight for scans.
“It’s been a crazy 24-hour emotional rollercoaster. The crazy thing is I was more concerned about my foot.
“The testicle had swollen to the size of a tennis ball and gone black and they spoke about counselling because it looked like I would lose it.
“I must thank first and foremost the club doctor John Lynagh and I can’t praise the staff of St James enough for how quickly and sympathetically they dealt with me.”
Mathers is in his second season at Wakefield, having spent last year on loan from Castleford.
He has previously played in Super League for Leeds, Wigan and Warrington, who the Wildcats are due to face this weekend.
