ENGLEWOOD, Colo. — Von Miller is expected to play Saturday when the Broncos take on the Minnesota Vikings, Head Coach Vance Joseph said Thursday.

Miller sat out three of the Broncos' four preseason games in 2017.

That will change Saturday.

"He's totally healthy," Joseph said. "He's had a great camp, and we have no reason not to play Von. Von's in good health and good spirits, so why not?"

Miller should play no more than two series when he joins the rest of the starters on the field.

"The first team will get two series, max," Joseph said. "Obviously things happen on game day, but just two series, max. After that we'll go with our twos, hopefully though the first half to probably the middle of the third quarter. And give our threes a chance to play probably third quarter to fourth."

Running backs Devontae Booker and Royce Freeman will likely split time with the first unit, Joseph said, while De'Angelo Henderson, Dave Williams and Phillip Lindsay will rotate with the second and third units.

Tight end Jake Butt will also receive snaps with the first unit, as starting tight end Jeff Heuerman was ruled out on Thursday. Joseph said Butt would play not much more than two series.

Safety Su'a Cravens and guard Menelik Watson were also ruled out, while linebacker Joe Jones and cornerback Tramaine Brock were deemed game-time decisions.

The Broncos have not yet made a determination on defensive end Clinton McDonald, who has missed the last two practice with a shoulder injury.

"He's still being evaluated," Joseph said. "Hopefully he can play Saturday. He wants to play. He's still being evaluated by the doctors."
