ENGLEWOOD, Colo. (AP) 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.

"It's a really minor thing. It's a scope," Joseph said. "It's probably an injury that if it had happened in the regular season he'd probably play in a couple of weeks. But we're going to take our time with this because we've got five weeks to get him healed up and get him ready for camp."
