When a player sustains an injury, often times the long-term concern shifts away from the actual area where the issue occurred to other parts of the body that may be impacted.
With a hamstring issue, it could be calves, hips or any part of the body over-compensating for the injured area.
"Hopefully," head coach Todd Bowles said via NJ.com, "he doesn't lose too much weight. You get stuff (plates and screws) in your jaw, I think it's going to be tough."
Bowles added: "I don't know exactly what he's eating. I'm assuming -- and I'm not a doctor, so don't quote me on this -- but you can drink protein shakes, or something from a straw."
Thinking about Smith's overall health after the 6-10 week recovery period lends some credence to the creeping rumors that he may be placed on short-term injured reserve, which would erase a huge chunk of the regular season.
Even if Smith loses 5-10 pounds during recovery, it will be 5-10 essential pounds he'll need to regain before putting himself through the rigors of an NFL football game.
