DENVER - Von Miller is set to have surgery to repair his torn right ACL in Florida on Thursday, and that means former Wallace-Rose Hill and NC State star Nate Irving will fill his spot on the defensive side of the ball when the Broncos host the Chargers.
Nate Irving has filled in at strongside linebacker in the base defense and defensive end Robert Ayers has subbed for Miller on passing downs. Irving has 41 tackles and one sack this season.
Miller's right knee buckled when he was blocked cleanly by Texans tight end Ryan Griffin in Denver's 37-13 win at Houston on Dec. 22. Miller's rehab is expected to take six to nine months, meaning he could miss the start of the Denver Broncos' training camp next summer.
That ended a rough season for the 2011 NFL Defensive Rookie of the Year, one that began with him serving a six-game drug suspension. He finished with five sacks in nine games.
