Sources: Broncos' Bo Nix had second procedure on right ankle

Denver Broncos quarterback Bo Nix had a second procedure on his surgically repaired right ankle during a follow-up visit with Dr. Norman Waldrop III last week in Birmingham, Alabama, sources told ESPN on Tuesday.

Nix still is expected to be ready for training camp, but his participation in the Broncos' offseason program, which is set to begin next Monday, could be limited, sources said.

Asked about Nix's recovery after the NFL draft concluded Saturday, coach Sean Payton confirmed the quarterback had a follow-up visit with Waldrop, who performed his initial surgery in January. Payton added: "He had a recheck that was scheduled. He's doing great. We're excited about his progress. Nothing to report."
