KANSAS CITY, Mo. -- Expect another heavy workload for Knile Davis this weekend. Rookie De'Anthony Thomas might be available for the first time in his NFL career, but Jamaal Charles is unlikely to play for the Kansas City Chiefs on Sunday when they play the Dolphins in Miami.

Coach Andy Reid said Charles has a high ankle sprain, and though Reid didn’t rule him out of the Dolphins’ game, he would probably need more recovery time before he’s ready to play.

"These things take time, but it doesn’t look to be a real severe one," Reid said. "What does that mean? We’ll see."

Charles was injured in the first quarter of Sunday’s 24-17 loss to the Broncos in Denver. He was replaced by Davis, who led the Chiefs in rushing with 79 yards on 22 carries. He also was the team leader in pass receptions with six and scored both of the Chiefs' touchdowns.

"I don’t think it will change much from what you saw (Sunday)," Reid said of Davis' likely role in Miami. "He was involved in a lot of different areas. I’m not saying number of carries or anything, but you saw him going in and playing a few different ways."

Thomas, the Chiefs’ fourth-round draft pick, has yet to suit up for a regular-season game because of a sore hamstring. Reid held out some hope he could play in Miami.

"He should be able to work himself back in this week," Reid said. "We’ll just see how he does once we get to Wednesday."

The Chiefs begin their practice week on Wednesday.

Safety Eric Berry also sprained an ankle in the Denver game. Reid indicated that injury wasn’t as severe as Charles' injury.
