Western Australian skipper Mitch Marsh says doctors initially feared he had ruptured a testicle in a training mishap.
Marsh was taken to hospital for scans after being struck in the groin while batting last week in the nets.
Doctors initially feared the worst, but surgery revealed it was only severe bleeding in the area rather than a rupture.
Marsh, ruled out of last week's Sheffield Shield loss to NSW, is set to return for the clash with South Australia, starting on Sunday at the WACA Ground.
"I basically got hit in the box by one of our coaches on the flicker," Marsh explained of the mishap.

"Usually, when you get hit in the box, it lasts for a couple of minutes and goes away. But after half-an-hour, I was in the exact same pain.
"I got taken to hospital to double check. I had a scan where they thought I potentially ruptured one of my testicles. But once they got in there, it was just basically severe bleeding.
"It was best-case scenario."
Marsh is still experiencing soreness, but is confident he'll be fine to tackle the Redbacks.
"Physically, I'm ready to go," Marsh said.
"I'm going to be pretty sore still going into the game, but that's fine. In that area, it's more a mental thing getting back into it.
"Once you get out in the middle and your competitive juices are flowing, I won't be thinking about this at all."
Marsh has endured a summer to forget after being dropped from Australia's Test, ODI and T20 sides.
The 27-year-old said the constant setbacks this summer were hard to swallow.
"It's been probably the most challenging eight months of my life in terms of cricket and all sorts of stuff," Marsh said.
"At times, I've certainly got down on myself, because you just want to do well and I love playing cricket.
"I probably got too down on myself and worked too hard and tried so much to try to score runs that I probably stopped enjoying the game at a point throughout the summer.
"Ultimately, I play the game to enjoy it with my mates and have fun.
"My next three weeks is about that and, hopefully, I'll be able to contribute with a few runs."
