Happened to me on Heavyweight with Mir, I think the key is... not to waste your stanima by attempting ground reversals... Just wait for him to attempt the sub, because somehow he'll always eventually get there, and quickly palm the joystick... this worked for me and Mir.. ended up standing back up... and BOOM KO! LMAO! Good luck guys!
another armbar oh well back to the store this game goes. i seriously don't get it my sub def is nearly 70 im like 4 years into career and i still cant beat the champ i've NEVER been knocked out my only loss is all these subs.
