WASHINGTON (AP) - A person familiar with the situation says Robert Griffin III will have surgery Wednesday to repair a torn ligament in his right knee.
The person said Griffin has a torn lateral collateral ligament and that the surgery will also determine whether he also has damaged the ACL.
The person spoke on condition of anonymity because the Redskins have not announced the latest details of Griffin's injury.
Baylor coach Art Briles confirmed the same details in an interview with USA Today.
A torn LCL would require a rehabilitation period of several months, possibly extending into training camp and the start of next season. A torn ACL is a more severe injury, typically requiring nine to 12 months of recovery.
Griffin reinjured the knee in Sunday's playoff loss to Seattle.
