Halftime notes from Denver

Posted by ESPN.com's Bill Williamson

DENVER -- Halftime thoughts from the Chiefs-Broncos game where Kansas City leads, 17-14:

Broncos rookie running back Peyton Hillis, who has 58 yards on eight carries, including an 18-yard touchdown run, departed the game with a strained hamstring. He is in the locker room. His return is questionable. Denver's only active tailback is Tatum Bell, who has played sparingly since signing three weeks ago. The Broncos will have to scrap the running game in the second half if Bell gets hurt.

The Chiefs have had three long returns in the first half.

Receiver Brandon Marshall is a big part of Denver's game plan. He has four catches in the first half.

Kansas City tailback Jamaal Charles has an ankle injury and is questionable to return.

Tight end Tony Gonzalez has caught a pass in 128 straight games.

Denver undrafted rookie linebacker Wesley Woodyard is having another big game. The Kentucky product has been terrific spelling D.J. Williams in the past five games. Next season, Denver will likely try to move Woodyard to strongside linebacker to get him on the field.
