Three key Kansas City defensive players are listed as questionable for Sunday’s season opener against visiting Atlanta.

On the official injury report, the Chiefs listed cornerback Brandon Flowers (foot), linebacker Derrick Johnson and linebacker Jovan Belcher (groin) as questionable for the game. Flowers and Johnson were limited at practice all week and Belcher was limited Friday after not practicing Thursday. Unless there are setbacks, I’d expect all three players to play.

The unit is expected to be without safety Kendrick Lewis (shoulder) and nose tackle Anthony Toribio (ankle). Both players didn’t practice this week and they are both listed as doubtful. The team will be without star pass-rusher Tamba Hali, who is serving a one-game NFL suspension.

So, no matter if Flowers, Johnson and Belcher are limited, the Chiefs will need them in any form they get on Sunday.
