Denver Broncos safety Omar Bolden and Kansas City Chiefs offensive lineman Jeff Allen joined the list of inactive players for Thursday as the two teams battle it out at the AFC West Division.

An AP report quoted by the New York Times noted that Bolden's absence will definitely affect the Broncos' defense and also other vital areas of their play since he is the top kick returner of the team.

Denver Post said Bolden, who injured his feet during the opener on Sunday, leads the list of inactive players like guard Shelley Smith, defensive end Kenny Anunike, quarterback Trevor Siemian, linebacker Lerentee McCray, tight end Mitchell Henry and cornerback Lorenzo Doss.

It was noted in the same report that the safety was not able to practice for this week due to his injury.

"In his absence, Andre Caldwell will start as the Broncos' kick returner, and Josh Bush will see more time at safety," added Denver Post.

Meanwhile, New York Times noted that Allen has been nursing a knee injury.

He joins other inactive players like quarterback Aaron Murray, rookie cornerback Steven Nelson, outside linebacker Dezman Moses, tight end Brian Parker, wide receiver Frankie Hammond Jr., and rookie defensive end Rakeem Nunez-Roches, as per Chiefs Digest.

To take his place, there are seven offensive linemen who can possibly pull out a great game for the Chiefs like Zach Fulton, Donald Stephenson, Ben Grubbs, Mitch Morse, Laurent Duvernay-Tardif, Jah Redia and Eric Fisher.

However, Chiefs Digest said that it is still uncertain if Fisher will continue to play right tackle since he is still recovering from a high-ankle sprain.

Meanwhile, Denver Post said Peyton Manning and Gary Kubiak are reportedly prepped up for their offense versus the Chiefs despite not displaying a less commendable performance on Sunday versus the Baltimore Ravens.

"We got out of whack, especially in the third quarter. What did we end up running the ball? Twenty-five times, and throw it 40 times? We would like to be balanced. That's one thing that we'd like to be, and hopefully we can get back there this week, but to be balanced you have to feel like you're making some headway running the ball and we weren't until the end of the game," explained Kubiak.

It was observed that the offense of the team was not solid since Manning was sacked four times.

"I think that I was the worst of the group. I would have liked us to be able to run the ball a little better. That kind of stuff is very valuable for it to happen where you can learn from it and not let it happen again," explained left guard Evan Mathis in the Denver Post report.
