ENGLEWOOD, Colo. — Cornerback Bryce Callahan is just a few months removed from suffering a broken foot in a Week 14 game against the Rams, but the Broncos' 2019 free-agent signing is nearly finished with his recovery process.

"Yes, he's ready," Fangio said Tuesday. "He actually could go in this camp, but we're just letting him do individual. I just want to give him a few more weeks to feel healthy."

Callahan participated in individual drills as the Broncos began their voluntary veteran minicamp.

Several other injured Broncos were also outside as the team stretched to begin the session, but Jake Butt, Emmanuel Sanders, Ron Leary and Phillip Lindsay soon moved to another field to work with trainers.

Fangio said Lindsay remains under the training staff's guidance.

"He's fine, but he just can't twist [his wrist] right now," Fangio said.

 Fangio did not provide an updated timetable for the return of either Lindsay or Butt.

"He's doing well in his recovery," Fangio said of Butt, who is recovering from a torn ACL. "Everything that we've been told is positive."

Sanders, meanwhile, is "progressing nicely" as he returns from an Achilles injury, Fangio said. 

One other Broncos veteran also stayed away from the field Tuesday, as cornerback Chris Harris Jr. chose not to participate in the Broncos' voluntary veteran minicamp.

Fangio, who said he hasn't spoken with Harris since the start of the offseason program, said he knows Harris' absence is "just part of the NFL landscape."

"It seems to happen a little bit each year," Fangio said.
