Just that it's a groin.
A notorious slow healer and he was already questionable with ankle and back ailments, and given he's had injuries this year already, expecting him back in 6 days seems like a long shot to me. But I could be wrong.
I would say Dallas is a bad opponent to have him missing against, but our secondary held up very well without him against a much better passing attack tonight. So if they played like they did today, we should be fine.
Cleveland wouldn't figure to be a game where he'd be that critical either.
That being said... Dallas is in dire straights. It's as close to a must-win game for them as it gets. 3-8, 12 days to prepare, and they'll need at least 3 more wins to have a shot at the division. They can't afford to lose much ground. A loss to the Ravens all but ends their season.
