Keenum returns to practice but three others sit out Thursday

Keenum fine to play Sunday at Baltimore, but LB Brandon Marshall, T Jared Veldheer and CB Adam Jones uncertain

Quarterback Case Keenum returned to practice on Thursday after sitting out Wednesday with a sore knee. Coach Vance Joseph said Wednesday that it wasn’t a serious situation and was confident Keenum would play Sunday at Baltimore.

The status of cornerback Adam Jones (thigh), linebacker Brandon Marshall (knee) and tackle Jared Veldheer (concussion protocol) are less clear for Denver’s first road game of the season. Veldheer took part in some team drills Thursday but sat out the contact session.

Joseph hasn’t ruled out Marshall for Sunday’s game.

“We have Friday, so I’m hopeful that Brandon will go (Friday),” Joseph told reporters after practice. “If he doesn’t go, it’ll be Josey (Jewell) in there full-time with Todd (Davis), and we’ll see how that goes from there.”

Jones, who signed just before the season, has been working his way into football shape. He has been the main punt returner and played in the secondary in passing situations but left in last Sunday’s win over Oakland with the thigh injury. Joseph wouldn’t say who would be the punt returner if Jones doesn’t play against the Ravens.

“We’ve got three or four guys that we can go to with that. I won’t share who it is right now, but I’m still hopeful Adam will work (Friday) and play on Sunday,” Joseph said.
