The Kansas City Chiefs remain hopeful that Spencer Ware will return at some point this season after the running back was carted off the field in the first quarter of Friday night's 26-13 preseason loss to the Seattle Seahawks with what the team later called a right knee injury.

A source told ESPN's Adam Schefter that Ware suffered a PCL injury and he will undergo an MRI on Saturday to determine extent of the injury and how much time he will miss. The timetable could be as little as two weeks and as many as eight, per the source, who added that Ware's ACL is thought to be fine.

"It's not one of those things that's just clear cut, end of the season," coach Andy Reid said Saturday. "That's not what it is right now. We've got to go through the whole process here in this case."

The team's top rusher last season, Ware was tackled after catching a short pass. He was holding his right knee before being taken from the field.

Reid said rookie Kareem Hunt, a third-round draft pick, will be the regular featured back in Ware's absence. Hunt averaged 4.3 yards per carry after Ware was injured in Friday's game.

"He'd be the next man up," Reid said.

The Chiefs have depth at running back, and Reid said veterans Charcandrick West and C.J. Spiller might also get some work.

"We've always rotated guys, and it would be no different, I think, in this case," Reid said.

The 229-pound Ware, the Chiefs' biggest and most physical runner, led the team with 921 rushing yards last season. He added another 447 yards receiving.
