Fellers, I would hate to be the voice of pessimism, but it seems he is done for the 2016 fantasy season, barring a miracle:

Updating previous reports, Cincinnati Bengals WR A.J. Green (hamstring) said he suffered a Grade 2 hamstring tear, and he's working to get back this season. It may not be until Week 17.
Holding onto Green is a nice idea for hope, but if you are in a pinch, it's not crazy to drop him. He is unlikely to play next week and it sounds like Week 15 is a stretch. If Week 16 if his first game back, we won't recommend trusting Green in your championship lineup.
