Ouch!! I feel your pain dude! I train in MT also. 4 years now. Nice to see some other MT fighters!
Being in contact sport, it's bound to happen. Unfortunately, it had to happen while training!
That's the worse! I always say, if you're gonna get injured, better be in the ring. All of my injuries happened in the ring actually. tore a ligament in my ankle once, and the other time i partially tore my mcl. Anyways, I hope for a speedy recovery! What school do you train at and who's your Kru?
How do you throw your hooks? I hope it's not with your wrist/palm facing you, rather your palm should be pointing down.
