Robert Griffin III is undergoing total reconstructive surgery of his right knee early Wednesday morning to repair torn anterior cruciate and lateral collateral ligaments.

Griffin, however, is expected to be ready for the 2013 regular season opener.

The torn ACL was diagnosed late Tuesday as a complete tear of the patella graft that was used to repair Griffin's torn ACL suffered at Baylor in 2009. 

Griffin's recovery is projected at six to eight months, barring any setbacks, sources said.
