Sage Stallone's Death

I just heard that Sage Stallone, Sylvester Stallone's son died recently at age 36.  That is sad news and my prayers go out to Sylvester Stallone and his family during this time of grief.  


Oddly enough, I just randomly thought of him the other day. I have been watching Heroes lately, which has Milo Ventimiglia in it (he played Rocky's son in Rocky 6) and it made me wonder why Sylvester Stallone's own son didn't play the part again like he did in Rocky 5.
