Big Cass is examined in the trainer's room after suffering a knee injury during his Brooklyn Street Fight against Enzo Amore.

AUG. 22 UPDATE: An initial MRI of Big Cass' left knee shows that he will require surgery.

"It looks like he has an ACL tear, possibly a medial meniscus tear, but we’re going to wait for the radiologist to evaluate the MRI and give us their full report," WWE ringside physician Dr. Chris Robinson said.

The seven-footer will be undergoing surgery this week to repair the damage, which will be the start of a long road back to the squared circle.

“A typical ACL tear takes about nine months [to recover from],” Robinson said.

ORIGINAL STORY: Big Cass suffered the injury to his left knee during the Brooklyn Street Fight against Enzo Amore on Raw. The injury occurred after Amore dodged a big boot by pulling down the top rope, sending Cass to the floor in the process.

“It’s hard to tell what the extent of the injury is, but we’re going to send him to get an MRI tomorrow and figure that out,” said WWE ringside physician Dr. Chris Robinson.
