Bruton, who suffered a dislocated left shoulder on a second-quarter kickoff Sunday night in the Broncos' 31-24 victory over the Indianapolis Colts, was on the field in a practice jersey but was without a helmet and did not participate. His arm was not in a sling.
"He's made improvement, but not ready to hit the field yet," Broncos head coach John Fox said.
Bruton suffered the injury when he was hit by Colts safety Colt Anderson on what was a touchback for the Broncos. Privately, many with the Broncos were not happy with Anderson's play on a Broncos kickoff that was not close to being returnable.
Bruton plays a variety of prominent roles on special teams, including personal protector on the punt team as well in the middle of the formation in kickoff coverage. If he either misses time or is limited, the Broncos would have several adjustments to make.
Also Wednesday, guard Ben Garland (ankle) worked with the team's strength and conditioning coaches but did not participate in practice. Fox said linebacker Danny Trevathan's recovery was on track from a fracture on the top of his tibia that he suffered in training camp.
Those were the only three injured players held out of practice. Linebacker Nate Irving, who left Sunday's game with a lower right leg injury but later returner, participated fully. All of the other Broncos players listed on the team's injury report, including left tackle Ryan Clady (foot), center Manny Ramirez (back), defensive end DeMarcus Ware (thigh), and cornerback Chris Harris Jr. (knee), practiced fully.
