KANSAS CITY, Mo. — The Kansas City Chiefs’ No. 1 weapon was on the sideline due to an ankle injury, but second-year running back Knile Davis produced a very Jamaal Charles-like performance against the Miami Dolphins on Sunday.

He fit right into coach Andy Reid’s offense, running 32 times for 132 yards and a 21-yard touchdown in the 34-15 victory.

“We knew we wanted to run it some,” Reid said. “I didn’t put a number on it, but it was working, we stuck with it.”

It was all positive production out of Davis with the exception of one thing — ball security. He fumbled twice, once in one of the worst spots for a back to ever give up the ball — in the fourth quarter trying to protect a lead. Davis recovered his own fumble on the other lost ball. They were the only blemishes on a performance that established Davis as the Chiefs best other running back in many years.

“You know, you get comfortable, you don’t see what’s around you and things happen,” Davis said of the fumbles. “You’ve got to keep two hands on the ball at all times. It’s that simple.”

Reid wanted to focus on the positives of Davis’ performance, knowing he’ll be able to drum home the ball security-issue in the coming practice week.

“He does need to keep it high and tight,” Reid said. “He’s always trying to get that extra yard and sometimes that’s where the ball gets loose on running backs. There’s a time when you just got to keep it in there tucked, get what you can and then get down.

“He was running very hard and he can learn from that. He’s a young guy. He didn’t play a ton last year because of Jamaal. You’ve got to give him credit for what he did today.”

Charles, scratched just before the game due to a sprained ankle, should be back to full work in practice on Thursday when the Chiefs return to the field for preparations to face New England in next week’s Monday night game.

–It has long been the so-called rule that punt returners place their heels on the 10-yard line and do not go backwards. They allow the ball to sail over their heads, hoping that it will bounce into the end zone. Catching the ball that deep in their own territory is asking for trouble and bad field position.

That wasn’t what punt returner Frankie Hammond did for the Chiefs against the Dolphins. He caught a punt at his own goal line and returned it 48 yards. But a penalty on the Chiefs for an illegal block set up the offense at their one-yard line, instead of the 48. On the first play, quarterback Alex Smith was sacked for a safety.

Later, Hammond caught a punt at the Chiefs four-yard line, this time he returned it 47 yards and gave the offense good field position at the Miami 49-yard line. Was this good or bad decision making by Hammond?

“We probably could have let a couple of those go,” Reid said. “Normally you let some go. They ended up being decent returns.”

Reid admitted the old philosophy on when and where to return punts and kickoffs is slowly dying away.

“The flavor of the day is that you are returning everything,” Reid said. “Kickoffs all the way to the end line and teams are bringing them out. Through studies it shows there’s production there. That’s not the way it was when I first got into the game; you would always let those go. Today it’s different.”

Notes: Safety Eric Berry is scheduled to return to practice on Thursday. Berry missed the Miami game due to a sprained ankle he suffered on Sept. 14 against the Broncos and did not practice all last week. … Running back/wide receiver De’Anthony Thomas (hamstring) is scheduled to return to practice on Thursday He practiced for the first time last Wednesday, but did not get back on the field because of muscle fatigue.
