While in Colombia recently TJ Ellis slammed his foot down wrong and screwed up a nerve in his right leg. His clothing sponsor Sullen has a good write up about his status on their site.
Here’s the nutshell version:
“TJ hit one of the jumps and slammed his foot down on the ground to catch himself from falling over. He didn't think much of this pain he had shooting through his leg because it would leave and then come back, then leave again so he opted out of the contest and became a judge. When he got home he went and saw a doctor and they said he had hurt his peroneal nerve in his right leg which controls the upward movement of his ankle and toes. The Doc said it's a nerve that will heal on its own and just to chill for a while.” – sullenclothing.com
