Why does Edgerrin James wear huge bandaids on his arm?

We also have gotten on his pics from Superbowl and can’t figure out what this is.

its to keep a separated or injured shoulder in place. it is sort of like an external muscle system that will limit some movement so the not-completely healed shoulder area won’t move too much. during the Olympics several athletes had them, notable one of the US women’s beach volleyball players

But it was located on his biceps not his shoulder.

I have seen devices like that for tendinitis. Is that possible?

Huge Cuts?
