A.J. Green is in the same group as Calvin Johnson now. He's got the toe injury, and the best course now is probably to have him sit out for 3-4 weeks and get it right. The team website suggests there's no chance Green will play this week.
This is the NFL, and there's always pressure for guys like Green to return before they're really healthy. So most likely, he'll sit for only 1-2 games. But he could become a Roddy White type guy, fighting this injury for much of the season.
For fantasy purposes, this is a big downgrade for Andy Dalton. It definitely adversely affects his numbers when he doesn't have his big gun in there.
We also can think some about Mohamed Sanu and Jermaine Gresham. Sanu is really the only wide receiver they have (Marvin Jones also won't play this week). Gresham is terrible, as evidenced by the dropped touchdown at Foxboro. But they really don't have much else, so Gresham (in my opinion) has a decent chance of being a top-15 tight end this week.
Gio Bernard can expect a big workload on Sunday, both as a runner and a pass catcher.
