Earlier this month, Chris Sabin went down at the most recent TV tapings at Center Stage in Atlanta, Georgia during a 6-way match. He had to be helped to the back, as seen in the photo below.
Afterwards, Ring of Honor did confirm he sustained a knee injury, but couldn't provide further details at the time.
Earlier today, Sabin announced he has a complete ACL tear and will be out 8-12 months.
