Since Crossen has also been limited in practice with a hamstring issue (beginning last Friday, the 14th), that seems to leave JC Jackson to round out active DB depth.
It's interesting that, in this particular instance, the loss of two active DBs seems unlikely to have a huge impact on ST. Ebner is currently top in ST snaps at 44, followed closely by King, Slater and JJ (probably all participating on all four units). Before missing the 2nd half last week, Chung had 16 ST snaps - on a pace for 22 total, probably only two units. Rowe has yet to play an ST snap this season (he typically only plays a relative handful of ST snaps during the season), so his absence isn't a factor there.
So, even if Crossen is significantly better on ST than Jackson, there's no reason to push him to play on a bad hammy. NOTE: I'm not saying that Crossen IS a better ST player than Jackson; it's just a hypothetical to illustrate the point.
I haven't personally been "told" by anyone that Crossen and Jackson are higher on the depth chart for DB scrimmage snaps than Cyrus - at least not by anyone whose authority on depth chart matters I'm willing to accept, which certainly doesn't include media reports. It's possible that they are, but that something that only the coaches themselves really know.
All I know is that Cyrus has had considerably more experience playing DB in the regular season than either of the rookies (147 snaps to zero), plus two full sets of OTAs, one full Camp and two partial Camps. So, I'll go with that until there's some tangible evidence to the contrary.
