Report: Robert Griffin III to Have Surgery on Torn LCL, Possibly ACL

Mike Shanahan‘s decision to keep Robert Griffin III in Sunday’s game despite obviously reaggravating a previous knee injury is looking worse by the day.

Griffin will have surgery this week to repair a torn LCL, according to Adam Schefter of ESPN.com. At the same time, doctors will determine if the Redskins’ quarterback’s ACL needs to be repaired as well.

Griffin underwent an MRI on Monday, and the results were inconclusive. The test showed damage to his LCL and ACL, but it was unclear whether those were new results, or remnants of past injuries to Griffin’s knee. He tore his ACL in 2009 while at Baylor, and he damaged his LCL this season.

Griffin is expected to be out most or all of the offseason, according to Jason La Canfora of CBS Sports. If Griffin’s ACL is torn, it could mean he’s out most of all of the 2013 season.
