Levy? Worth stashing? Will he ever play?

I am in a league that starts 10 IDP players so value on a good LB is very high with very thin bench space.  We score 2 pts per tackle too.  My team is a shoe in for playoffs so looking towards weeks 14-16... I have been sitting on Levy for weeks now but NFL is horrible at posting injury status on defensive players.

Does anyone know what his injuries are?
Is he worth waiting on for down the stretch?
Should I drop Him?

If I drop I can start any position to replace him and these guys are available. (again tackle heavy league 2pts per but no assists)
Nick Bellore
Perry Riley
Clayton Geathers
Duke Ihenacho
Calvin Pryor
D.J. Swearinger
Joey Bosa etc....

Thanks for any input!

Jim Caldwell and the Lions have been very mum on his injury. Given his prior history, I've been assuming he will be out for a while. And I'm not sure how he will play even when he returns. Geathers is probably your best option of those available. Kind of depends on who your current linebackers are right now. If you are stacked at the position, that probably safe to drop Levy in a redraft league.
