ENGLEWOOD | One of the Denver Broncos’ biggest offseason stars, Adam Gotsis, missed the final day of mandatory minicamp Thursday to undergo arthroscopic surgery on his right knee. Coach Vance Joseph said he expects the rising second-year defensive lineman to be back by the first week of training camp, which begins July 27.

“The guys in the front office definitely got a tough decision to make in terms of who they’re going to keep because every guy out here’s been making plays,” said Sanders, who enjoyed a day off Friday. “It’s a very positive thing that we’ve got so much depth that they have to make a tough decision. I feel like the wide receiver corps can be the central point of this offense and this team.”
