During the 2005 season, the Browns attempted to convert Lang to linebacker in their new 3-4 scheme under head coach Romeo Crennel. The position change was generally considered to be unsuccessful, however, and Lang was released in February 2006. On March 18, 2006, Lang signed with the Denver Broncos. The Broncos released him on August 27, 2007.
Lang coached at Jones High School in Orlando, Florida in 2008. He took a team that was 1-9 in 2007 and turned them into a playoff team in his first season. He also founded the Kenard Lang Foundation, which focuses on cancer, youth and education. Starting with the 2013 season, Lang was named head coach at Wekiva High School in Apopka, Florida
