( - The news regarding Robert Griffin III's injured knee has gone from bad to worse.

ESPN's Chris Mortensenreported early Wednesday morningthat the Washington Redskins quarterback will undergo total reconstructive surgery later today to repair torn anterior cruciate and lateral collateral ligaments in his right knee.

Mortensen, citing team sources familiar with the determination made by orthopedic specialist Dr. James Andrews, reports that Griffin's recovery time is expected to be six-to-eight months, meaning he should be ready for the Redskins' 2013 regular-season opener. Without any setbacks, Griffin, who tore his ACL before in 2009, should be able to participate in training camp in August.

A team source told Mortensen that Dr. Andrews is likely to use a patella graft from Griffin's left knee to repair the torn ACL. While the reconstruction of the LCL is considered complicated, Dr. Andrews informed the Redskins that it should be able to rehab well simultaneously with the repaired ACL.

While Art Briles couldn't confirm the extent of the damage to Griffin's knee Tuesday, the Baylor coach expressed confidence in Griffin's ability to recover from any setback.

"Robert will do what he always does, he'll rise again," Briles told USA TODAY Sports. "He just attacked that ACL tear, which is what he's done with everything he's ever been involved with, intellectually or athletically.

"Whatever it is, come next fall, Robert will be Robert. Whatever the outcome winds up being, he'll attack it just like he attacks everything else -- with a lot of fearless confidence and great effort."
