No way Jeff would have called Colton out for faking appendicitis had that not been the case. He was probably given an antibiotic as a cover their a$$ move. It must have been very obvious to the doctor that nothing serious was going on.
I think a doctor came to camp and put Tyson's shoulder back in place and gave him some pain meds. It was not totally out and the medic said you may have damaged a tendon. The sling was just to keep it immobile to lessen the pain and prevent further damage until he could be seen. I have a hunch he will be fine. This may work to his advantage in that he will not be seen as an II threat at the merge. He is in a strong alliance so he won't be voted out because of this anytime soon.
