Ask WhiskyBreath if that would be possible. My bone was splinted, not surgically repaired, so I had to sleep sitting up (at Doctor's orders) for 5 weeks, or the bone would not have healed correctly, not to mention that it was excruciatingly painful to lay down and get up. Since you know as little about anatomy as you do about baseball, I'll tell you that the humerus is the second biggest bone in the body, and since it wasn't surgically repaired and it is very difficult to immobilize without surgery, you really can't do much of anything. Football players play with cracked ribs, but you'll never see any athlete play anything with a broken humerus. I am yet to see a player who has suffered the injury who was not taken from the field on a stretcher.
