--Tight end Tony Scheffler caught four passes for 54 yards in Denver's first preseason game.
--Receiver Brandon Marshall, who was making a push for the third receiver job, suffered a knee injury against Detroit and could miss a couple weeks. The injury isn't considered serious, however.
--Defensive lineman Elvis Dumervil had a solid game against Detroit. The Broncos are thin at defensive tackle and need Dumervil to provide some depth.
--Linebacker Cameron Vaughn got a lot of playing time with the second-team defense. He is having a good camp and could make the team.
--Defensive tackle Antwon Burton will benefit from Gerard Warren's absence while he recovers from dislocated toe. Burton is a big body in the middle and has been playing with the second-team defense.
--Tailback Mike Bell's fumble against Detroit probably won't cost him the starting job for now. But his margin of error got smaller after that play.
