Chiefs’ Jamaal Charles and Phillip Gaines undergo surgery

Running back Jamaal Charles, who tore his anterior cruciate ligament against the Chicago Bears on Oct. 11, underwent surgery on his right knee Tuesday with Dr. James Andrews.

Meanwhile, Chiefs coach Andy Reid said cornerback Phillip Gaines, who tore the ACL against Green Bay on Sept. 28, had surgery on his left knee last week, which was also done by Andrews.

“Reports were good,” Reid said.

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.

Steelers injuries

Pittsburgh quarterback Ben Roethlisberger was a limited participant Wednesday as he recovers from an MCL sprain and bone bruise he suffered in a 12-7 win the St. Louis Rams on Sept. 27. He has missed the Steelers’ last three games, but Pittsburgh has gone 2-1 without him.

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.

Other injured players missed practice include outside linebacker James Harrison (not injury related), tight end Matt Spaeth (not injury related) and quarterback Mike Vick (hamstring).
