NFL Network Insider Ian Rapoport and NFL Networks Tom Pelissero reported Wednesday that James suffered a knee injury that is not season-ending.
It's unclear at this stage how much time the right tackle will miss but avoiding a season-ender offers a modicum of positive news for Denver.
James left Monday night's loss in Oakland after just eight offensive snaps.
The injury thrusts Elijah Wilkinson into the starting role until James returns. The third-year pro started seven games in Denver in 2018.
Here are other injuries we are monitoring around the league on Wednesday:**
On another note in Cincinnati, RB Joe Mixon (ankle) is considered day-to-day and coach Zac Taylor said he will manage his practice load this week to better his chances of playing on Sunday. Mixon left the season-opener early after sustaining the injury, and a follow-up MRI concluded there was no structural damage. Giovanni Bernard would get the lead role at RB should Mixon be out. Tackle Cordy Glenn remains in the league's concussion protocol and the Bengals waived QB Jeff Driskel with an injury settlement.
- Carolina Panthers edge rusher Bruce Irvin (hamstring) has been ruled out for Thursday night's home game against the Buccaneers. Tight end Greg Olsen (back) practiced in full on Wednesday and is officially listed as questionable. Rookie tackle Greg Little (concussion) was a full participant in practice all week after being in concussion protocol for the extent of Week 1. Safety Rashaan Gaulden (groin) is also questionable after being limited in practice on the eve of game day.
- Tampa Bay Buccaneers backup QB Blaine Gabbert (left shoulder) did not practice all week and is ruled out for Thursday night. Gabbert is Tampa Bay's only player with an injury designation in the shortened week.
- Chicago Bears coach Matt Nagy calls TE Trey Burton (groin) day-to-day, and said playing him would be a decision made on game day.
The team also announced they have waived defensive lineman Abdullah Anderson and have been awarded via waivers TE J.P. Holtz.
- The Dallas Cowboys listed the following players on today's injury report: WR Tavon Austin (concussion), DE Tyrone Crawford (hip), LB Luke Gifford (ankle) and G Zack Martin (back) all didn't practice while safeties Darian Thompson and Donovan Wilson -- both are dealing with ankle injuries -- were limited.
- Washington Redskins TE Jordan Reed (concussion) took part in team drills on Wednesday, coach Jay Gruden revealed. Reed suffered the concussion on the second to last preseason game, which kept him out of Week 1. Safety Montae Nicholson (foot) missed practice.
The team later released their full injury report and listed the following players: DL Jonathan Allen (knee), DT Caleb Brantley, RB Derrius Guice (knee) and QB Colt McCoy (fibula) also didn't practice. CBs Quinton Dunbar (knee) and Fabian Moreau (ankle) were limited participants.
- San Francisco 49ers edge rusher Nick Bosa (ankle) did not practice on Wednesday due to soreness. Bosa played most of the defensive snaps last Sunday and even recorded a sack in his NFL debut, but limped off the field after the last play thanks to the same ankle that kept him out for most of the offseason. Safety Jimmie Ward (hand) was limited, while wide receivers Jalen Hurd (back) and Trent Taylor (foot) missed practice.
- New York Giants WR Sterling Shepard (concussion) did not practice Wednesday, while guard Kevin Zeitler (shoulder), DL Dexter Lawrence, and LB Markus Golden (shoulder) were all limited.

Cornerback Craig James was promoted to the active roster from the practice, where tight end Alex Ellis was signed to.

- The Houston Texans announced updates for several injured players: QB Deshaun Watson (back), S Justin Reid (shoulder), G Tytus Howard (finger) and WR Keke Coutee (ankle) were among the full participants in today's practice.
