RG3's father: ACL partially intact

When Robert Griffin III underwent surgery early Wednesday to repair his torn right lateral collateral ligament, it was determined that his right anterior cruciate ligament was also damaged and needed reconstructive surgery for a second time since 2009, Griffin's father told USA TODAY Sports.

The surgery was performed by renowned orthopedist James Andrews in Pensacola, Fla, and began early Wednesday as scheduled after MRI's initially showed no evidence of the ACL tear, according to Griffin II.

"Robert's ACL is intact, but not enough for his profession,'' Griffin II said in a text message to USA TODAY Sports. "You and I could be fine. But he is an athlete. So they will replace.''

The timetable for Griffin's recovery is unknown at this point, but renowned orthopedist Dr. Neal ElAttrache told USA TODAY Sports that, with a typical isolated ACL reconstruction, it takes at least six months for a skill-position player to get back on the field doing position-specific drills.

Griffin suffered a Grade 1 sprain of the LCL during a Dec. 9 game against the Baltimore Ravens and after missing the next game against Cleveland, But he aggravated the knee early in Sunday's wild-card game and then was forced from the field when his knee buckled in the fourth quarter.
