The Broncos listed four players as questionable on the final injury report before playing the Baltimore Ravens Sunday.

Cornerback Adam Jones (thigh), linebacker Brandon Marshall (knee), safety Dymonte Thomas (abdomen) and tackle Jared Veldheer (concussion) are all questionable for the matchup. Veldheer and Marshall were able to participate in Friday’s practice in a limited fashion while Jones and Thomas did not participate.

After missing practice with knee soreness earlier in the week, quarterback Case Keenum was a full participant in the final two days of practice. Nose tackle Domata Peko also missed practice on Tuesday, but it was a rest day for the veteran.

Head coach Vance Joseph was not overly concerned with the absences given that three of the four are veterans.

“To play without practice from Adam or even B-Marsh, I’m OK with that,” Joseph said. “They’re experienced football players, they know our system. It’s only Week 3 so we’re being smart with our guys so we don’t lose these guys for the long term.”

After beginning the season with two home victories, Denver’s trip to Baltimore will be their first road test of the season. The game will kick off at 11 a.m. MT.
