Marshall expects to play, Aqib Talib, Julius Thomas questionable

ENGLEWOOD, Colo. -- With a rather substantial list of defensive backs dotting the team’s injury report the Denver Broncos may have to adjust some things in Sunday night’s AFC West showdown against the Kansas City Chiefs.

Following Friday's practice Broncos head coach John Fox said cornerback Kayvon Webster (right shoulder) is out for the game while cornerback Aqib Talib (left hamstring) and safety Quinton Carter (knee) are questionable. Webster did not take part in Friday’s practice while Talib and Carter were both limited in the workout.

Talib did not practice Wednesday or Thursday. If Talib and Carter are limited or don’t play, the Broncos will look to Omar Bolden, who has played both safety and cornerback, as well as cornerback Tony Carter.

The question on Talib will be whether or not the Broncos feel like he can make it through the game if they put him in uniform Sunday night. In the win against the Miami Dolphins last Sunday, Talib left the game in the first quarter. He tried to return later in the first half, but didn’t play in the second half and the Broncos had made Carter a game-day inactive.

“We’ll decide how exactly it’s going to play out,’’ said defensive coordinator Jack Del Rio. “We’ll just let it unfold. We prepare all our guys.’’

Also Friday, tight end Julius Thomas (left ankle) took part on a limited basis for the second consecutive day. Fox said following the practice that Thomas looked “much better’’ Friday than he did last Friday.

Thomas did not play last week. The Broncos hope Thomas will improve before it leaves for Kansas City.

Linebacker Brandon Marshall, who suffered a concussion in the fourth quarter of the Broncos’ win over the Dolphins last Sunday, was cleared by an independent physician as well as the Broncos’ medical staff to return to practice Friday.

Marshall, who plays in all of the team’s personnel groupings on defense, said he expects to play Sunday night in Arrowhead Stadium and take his “normal’’ number of snaps.

“Big game, everybody wants to win this game, this is the biggest game of our season so far,’’ Marshall said. “I’m just glad the concussion wasn’t too bad. I’ve been studying all week even thought I haven’t been practicing, but I’ve been paying attention. I’m just glad to be back out there.’’

As expected, Fox formally ruled out running backs Montee Ball (right groin) and Ronnie Hillman (left foot) for Sunday’s game.

Defensive end Quanterus Smith (ankle) participated fully in Friday’s practice and is expected to play.
