titanium rod was put in his leg and they said very optimistically that he would be 9 months before he could begin training.
Realistically he's 38, not old by most standards but in mma, he's past his prime, and wounds heal slowly. Anyone that watches Louisville basketball remembers Kevin Ware. His broken leg was much like Silva's, a complete fracture of the tibia and fibula, but his broke the skin. Ware is still not going to play this year so his recovery will take nearly 2 years. I assume Silva will try and come back, but even a year + recovery time puts him at almost 40, and as mentioned, his leg will be a giant target.
