Torn biceps tendon count ? I let mine go and it took 6 months to get to 85% and my arm , literally, looks like pop-eyes-nature of the beast . A complete tear usually calls for surgery -especially the elbow -you'll be lucky to get him back in 6 months -waiting and so much scar tissue will form the kid will have to have 'open' surgery' rather than a scope-which i'm assuming the want to do.
i tore my left biceps tendon, the one at the elbow. no surgery. i took at least 6 months or more to get to 80ish percent as well. but i could do a lot of stuff with it in the mean time. but wrestle?, not likely.
