Thomas misses practice, may miss game

KANSAS CITY, Mo. -- Rookie De'Anthony Thomas has a sore hamstring and won't practice Thursday for the Kansas City Chiefs. His availability was unclear for Sunday's game against the Tennessee Titans at Arrowhead Stadium.

"We really don't know how bad it is or how long it will be," coach Andy Reid said.

Replacing Thomas isn't as easy as plugging in the next guy in line. Thomas is unique in the Chiefs' offense in that he lines up on various occasions in different spots: slot receiver, wide receiver and as a running back.

If he can't go against the Titans, several players would be more prominent in the Chiefs' offensive plans, including Junior Hemingway, Albert Wilson, Joe McKnight and A.J. Jenkins. But none of those players is as fast as Thomas.

Thomas is the Chiefs' punt returner as well, and the team would also like to use him as a change of pace from Knile Davis on kickoff returns.

Frankie Hammond Jr., Wilson or McKnight would replace Thomas as a punt returner.

"We've got a lot of guys that can do it," special teams coordinator Dave Toub said. "If that's the case, I think we'll be fine. The good thing is it's not severe. He'll be back."

Starting cornerback Marcus Cooper also won't practice because of a sore ankle, though Reid held out hope he would play against the Titans. He will be replaced in the starting lineup by Ron Parker.
