KANSAS CITY, Mo. (AP) — Kansas City Chiefs running back Spencer Ware has been ruled out of Sunday's game against Jacksonville with a concussion, though wide receiver Jeremy Maclin and defensive tackle Jaye Howard will be available.
Maclin returned to practice Friday after tweaking his hamstring earlier in the week, while Howard was back after dealing with a hip injury he suffered last weekend against Indianapolis.
Alex Smith had already been ruled out with a head injury. Nick Foles will start at quarterback.
Others who have been ruled out include offensive lineman Parker Ehinger, who has a knee injury that could be season ending, and cornerback D.J. White, who is recovering from a fractured hand.
Offensive lineman Mitchell Schwartz, who was dealing with a sore ankle, and linebacker Derrick Johnson, who missed time with a sore hamstring, practiced Friday and will be available against the Jaguars.
Ware is a substantial loss for the Chiefs (5-2), though, not only because he's having a breakthrough season but also because Jamaal Charles has been placed on injured reserve after having his meniscus repaired.
Chiefs coach Andy Reid said Friday he's unsure whether Charles will be back this season.
"I haven't even got that far," he said. "I can't tell you that."
The Chiefs will face the Jaguars with Charcandrick West getting the bulk of the carries, and Bishop Sankey spelling him — despite only signing with Kansas City this week. The 2014 second-round draft pick of Tennessee had been on the Patriots' practice squad before getting the call.
Reid is confident Sankey knows enough of the offense to help out Sunday.
"He had a lot thrown at him. It was like learning French overnight," Reid said. "It's a tough deal but he hung in there and I thought he did a respectable job."
The Chiefs could have brought up Darrin Reaves from the practice squad, but he tweaked a groin muscle before they were able to make the move. Reaves was with the team all through training camp, had a couple of solid preseason games, and would have offered a much better grasp of the offense.
"It was bad timing," Reid said, "because he's a pretty good little player. He tweaked that thing, so we didn't have an opportunity to bring him up."
