J.J. Watt's groin injury turned out to be a lot more serious than initially thought, according to a report from ESPN.com.
The report claims Watt played through multiple partial and full groin tears throughout the 2015 season. Specifically, he had a partially torn left and right abdominals, a partially torn right adductor longus, a fully torn left adductor longus and a fully torn left adductor pectineus. According to ESPN, these are muscles in the core area.
