I am not a Forrest fighter fan and never was, I am however a Forrest the person fan. I think he ran out because like others have mentioned, he was embarrassed. Also Forrest is one fighter that really gives a crap about how his fans and MMA fans in general see him. When he lost against Jardine, and cried afterwards he got a lot of flack from people. I'm pretty sure that once he got his head back he started to tear up and didn't want anyone to see him that way. I'm sure it wasn't meant to be a disrespect of his opponent.
