Rookie Thomas likely won't play vs. Titans

KANSAS CITY, Mo. -- De'Anthony Thomas' NFL debut will likely have to wait until Week 2, or possibly later. The Kansas City Chiefs listed Thomas as doubtful for Sunday's game against the Tennessee Titans because of a sore hamstring.

The Chiefs are already missing suspended wide receiver Dwayne Bowe for the Titans game.

Thomas' loss might hurt most as the punt returner. Frankie Hammond Jr. should get most or all of the work there on Sunday.

But the Chiefs also will miss Thomas on offense, where he was lining up as both a receiver and running back. His absence could mean more plays on offense for Junior Hemingway, Albert Wilson, A.J. Jenkins and Knile Davis.

Starting cornerback Marcus Cooper (ankle) was listed as questionable for Sunday's game. If Cooper doesn't play, Ron Parker would move into the starting lineup. Rookie Phillip Gaines, who looked lost in last week's preseason game, would also move up on the depth chart and the Chiefs might have to play him at least a few snaps if Cooper doesn't play.
