Jona Nareki put his balls on the line to help Otago win the Log o' Wood last week.
The Otago winger suffered a ruptured testicle midway through the second half of the Ranfurly Shield match-up against Waikato in Hamilton.
"I can't really explain the pain," Nareki told Radio Hauraki's The Matt & Jerry Show. "I could only lie down to ease the pain away. For a minute there I had to get up and run again."
The Shield match was a classic, going down to the wire with Otago ultimately securing the shield for the summer with a 23-19 victory over Waikato.
