Shogun has rumored to have been returning 3 times this year already. Lets see him training for an actual scheduled fight before we get our hopes up.
ACL injuries are career enders for many. In the NFL, an ACL injury usually means you're out for a year and never the same even when you return. I just don't know how effective he will be and where his mind will be once he does get back.
I hope he comes back with a vengeance but torn knee ligaments are no joke. All of your mobility hinges on that knee ligament.
