ENGLEWOOD, Colo. —The Broncos were without two starting members of their secondary during Wednesday's practice as safety Darian Stewart (neck) and cornerback Bradley Roby (ankle) were held out.

"I have no concern," Head Coach Vance Joseph said when asked about the team's secondary depth. "We have guys that are capable. At corner, we have two veterans in [Tramaine] Brock and Adam Jones, along with Isaac [Yiadom]. Brock's played really well the last two weeks. I've been really impressed with him. And Adam Jones is healthy now. I have no concerns there.

"I thought Justin [Simmons] played really well last week, and I thought Parksy [Will Parks] had his moments where he did some good stuff, but also had some bad plays. He'll learn from those. Dymonte Thomas is here, Shamarko Thomas. So we've got capable guys, we really do."

Linebacker Brandon Marshall (knee), wide receiver DaeSean Hamilton and running back Royce Freeman (ankle) also did not practice.

Outside linebackers Shane Ray (ankle/wrist) and Von Miller (knee) and tackle Jared Veldheer (knee) were limited.

Veldheer hadn't practiced since he suffered an injury in Week 4 against the Chiefs. 

The Broncos could also get wide receiver Jordan Taylor and safety Su'a Cravens back for Sunday's game. Taylor (PUP) and Cravens (IR) havemissed the first eight games of the season.

"Jordan had a good day today, he's doing fine, and Su'a's been good for about a week and a half," Joseph said. "So obviously those guys are ready to come up to the roster. A move has to be made to get them up, so we'll see." 

The Broncos currently have 52 players on their active roster.

If Cravens returns for Sunday's game against the Texans, he could also help the Broncos' secondary depth.

"I think Su'a is a natural, in-the-box, dime linebacker," Joseph said. "With all the passing game that you're seeing on first, second down out of three-wide, he's a perfect fit. … We'll see how the week goes, but he's excited, he's healthy and he wants to help."
