Four key Chiefs miss practice Wednesday
Four Chiefs starters missed practice Wednesday due to injuries: receiver Jeremy Maclin (concussion), defensive end Mike DeVito (concussion), outside linebacker Tamba Hali (knee swelling) and inside linebacker Ramik Wilson (knee/ankle).
“All those guys are making progress in the right direction,” Reid said.
Nose tackle Dontari Poe (ankle) and inside linebacker Josh Mauga (groin/Achilles), missed Sunday’s game against the Minnesota Vikings but both practiced Wednesday. Mauga was a full participant, while Poe was limited.
Outside linebacker Justin Houston (elbow) was a limited participant in practice.
Receiver Chris Conley (knee), tight end Travis Kelce (facial laceration), kicker Cairo Santos (right foot) and quarteback Alex Smith (right thumb) were all full participants.

Four Steelers starters missed practice in safety Will Allen (ankle), cornerback Antwon Blake (thumb), cornerback William Gay (not injury related) and defensive end Stephon Tuitt.
