ATHENS — Nick Chubb will require surgery on his knee, according to his mother, but the extent of the injury is still unclear.

“It’s not nearly as bad as it could’ve been,” La’Velle Chubb wrote in a Facebook post on Sunday morning.

Nick Chubb tore his PCL (posterior cruciate ligament) along with two other ligaments, according to his mother’s post.

“They’ll wait for swelling to go down to decide when to have surgery. Possibly two (weeks),” La’Velle Chubb wrote. “Nick is in good spirits.”

Chubb injured his left knee on the first play from scrimmage in Georgia’s 38-31 loss at Tennessee. It looked gruesome at first, but head coach Mark Richt said after the game he was “hopeful” it wouldn’t require surgery. Apparently it will, but it’s not clear how extensive the damage is and whether the dreaded ACL tear has occurred.

Update: Nick Chubb is out for the season
