It depends on how the supposed loss would happen. If Condit lands a killer leg kick to injured area and GSP is hobbled for the rest of the fight, then yeah it would be safe to say it was due to the injury. If he just straight up beats GSP (not gonna happen), I won't blame ring rust. I don't believe in ring rust.
